-# Azure Active Directory authentication for Go
-
-This is a standalone package for authenticating with Azure Active
-Directory from other Go libraries and applications, in particular the [Azure SDK
-for Go](https://github.com/Azure/azure-sdk-for-go).
-
-Note: Despite the package's name it is not related to other "ADAL" libraries
-maintained in the [github.com/AzureAD](https://github.com/AzureAD) org. Issues
-should be opened in [this repo's](https://github.com/Azure/go-autorest/issues)
-or [the SDK's](https://github.com/Azure/azure-sdk-for-go/issues) issue
-trackers.
-
-## Install
-
-```bash
-go get -u github.com/Azure/go-autorest/autorest/adal
-```
-
-## Usage
-
-An Active Directory application is required in order to use this library. An application can be registered in the [Azure Portal](https://portal.azure.com/) by following these [guidelines](https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-integrating-applications) or using the [Azure CLI](https://github.com/Azure/azure-cli).
-
-### Register an Azure AD Application with secret
-
-
-1. Register a new application with a `secret` credential
-
-   ```
-   az ad app create \
-      --display-name example-app \
-      --homepage https://example-app/home \
-      --identifier-uris https://example-app/app \
-      --password secret
-   ```
-
-2. Create a service principal using the `Application ID` from previous step
-
-   ```
-   az ad sp create --id "Application ID"
-   ```
-
-   * Replace `Application ID` with `appId` from step 1.
-
-### Register an Azure AD Application with certificate
-
-1. Create a private key
-
-   ```
-   openssl genrsa -out "example-app.key" 2048
-   ```
-
-2. Create the certificate
-
-   ```
-   openssl req -new -key "example-app.key" -subj "/CN=example-app" -out "example-app.csr"
-   openssl x509 -req -in "example-app.csr" -signkey "example-app.key" -out "example-app.crt" -days 10000
-   ```
-
-3. Create the PKCS12 version of the certificate containing also the private key
-
-   ```
-   openssl pkcs12 -export -out "example-app.pfx" -inkey "example-app.key" -in "example-app.crt" -passout pass:
-
-   ```
-
-4. Register a new application with the certificate content form `example-app.crt`
-
-   ```
-   certificateContents="$(tail -n+2 "example-app.crt" | head -n-1)"
-
-   az ad app create \
-      --display-name example-app \
-      --homepage https://example-app/home \
-      --identifier-uris https://example-app/app \
-      --key-usage Verify --end-date 2018-01-01 \
-      --key-value "${certificateContents}"
-   ```
-
-5. Create a service principal using the `Application ID` from previous step
-
-   ```
-   az ad sp create --id "APPLICATION_ID"
-   ```
-
-   * Replace `APPLICATION_ID` with `appId` from step 4.
-
-
-### Grant the necessary permissions
-
-Azure relies on a Role-Based Access Control (RBAC) model to manage the access to resources at a fine-grained
-level. There is a set of [pre-defined roles](https://docs.microsoft.com/en-us/azure/active-directory/role-based-access-built-in-roles)
-which can be assigned to a service principal of an Azure AD application depending of your needs.
-
-```
-az role assignment create --assigner "SERVICE_PRINCIPAL_ID" --role "ROLE_NAME"
-```
-
-* Replace the `SERVICE_PRINCIPAL_ID` with the `appId` from previous step.
-* Replace the `ROLE_NAME` with a role name of your choice.
-
-It is also possible to define custom role definitions.
-
-```
-az role definition create --role-definition role-definition.json
-```
-
-* Check [custom roles](https://docs.microsoft.com/en-us/azure/active-directory/role-based-access-control-custom-roles) for more details regarding the content of `role-definition.json` file.
-
-
-### Acquire Access Token
-
-The common configuration used by all flows:
-
-```Go
-const activeDirectoryEndpoint = "https://login.microsoftonline.com/"
-tenantID := "TENANT_ID"
-oauthConfig, err := adal.NewOAuthConfig(activeDirectoryEndpoint, tenantID)
-
-applicationID := "APPLICATION_ID"
-
-callback := func(token adal.Token) error {
-    // This is called after the token is acquired
-}
-
-// The resource for which the token is acquired
-resource := "https://management.core.windows.net/"
-```
-
-* Replace the `TENANT_ID` with your tenant ID.
-* Replace the `APPLICATION_ID` with the value from previous section.
-
-#### Client Credentials
-
-```Go
-applicationSecret := "APPLICATION_SECRET"
-
-spt, err := adal.NewServicePrincipalToken(
-	oauthConfig,
-	appliationID,
-	applicationSecret,
-	resource,
-	callbacks...)
-if err != nil {
-	return nil, err
-}
-
-// Acquire a new access token
-err  = spt.Refresh()
-if (err == nil) {
-    token := spt.Token
-}
-```
-
-* Replace the `APPLICATION_SECRET` with the `password` value from previous section.
-
-#### Client Certificate
-
-```Go
-certificatePath := "./example-app.pfx"
-
-certData, err := ioutil.ReadFile(certificatePath)
-if err != nil {
-	return nil, fmt.Errorf("failed to read the certificate file (%s): %v", certificatePath, err)
-}
-
-// Get the certificate and private key from pfx file
-certificate, rsaPrivateKey, err := decodePkcs12(certData, "")
-if err != nil {
-	return nil, fmt.Errorf("failed to decode pkcs12 certificate while creating spt: %v", err)
-}
-
-spt, err := adal.NewServicePrincipalTokenFromCertificate(
-	oauthConfig,
-	applicationID,
-	certificate,
-	rsaPrivateKey,
-	resource,
-	callbacks...)
-
-// Acquire a new access token
-err  = spt.Refresh()
-if (err == nil) {
-    token := spt.Token
-}
-```
-
-* Update the certificate path to point to the example-app.pfx file which was created in previous section.
-
-
-#### Device Code
-
-```Go
-oauthClient := &http.Client{}
-
-// Acquire the device code
-deviceCode, err := adal.InitiateDeviceAuth(
-	oauthClient,
-	oauthConfig,
-	applicationID,
-	resource)
-if err != nil {
-	return nil, fmt.Errorf("Failed to start device auth flow: %s", err)
-}
-
-// Display the authentication message
-fmt.Println(*deviceCode.Message)
-
-// Wait here until the user is authenticated
-token, err := adal.WaitForUserCompletion(oauthClient, deviceCode)
-if err != nil {
-	return nil, fmt.Errorf("Failed to finish device auth flow: %s", err)
-}
-
-spt, err := adal.NewServicePrincipalTokenFromManualToken(
-	oauthConfig,
-	applicationID,
-	resource,
-	*token,
-	callbacks...)
-
-if (err == nil) {
-    token := spt.Token
-}
-```
-
-#### Username password authenticate
-
-```Go
-spt, err := adal.NewServicePrincipalTokenFromUsernamePassword(
-	oauthConfig,
-	applicationID,
-	username,
-	password,
-	resource,
-	callbacks...)
-
-if (err == nil) {
-    token := spt.Token
-}
-```
-
-#### Authorization code authenticate
-
-``` Go
-spt, err := adal.NewServicePrincipalTokenFromAuthorizationCode(
-	oauthConfig,
-	applicationID,
-	clientSecret,
-      authorizationCode,
-      redirectURI,
-	resource,
-	callbacks...)
-
-err  = spt.Refresh()
-if (err == nil) {
-    token := spt.Token
-}
-```
-
-### Command Line Tool
-
-A command line tool is available in `cmd/adal.go` that can acquire a token for a given resource. It supports all flows mentioned above.
-
-```
-adal -h
-
-Usage of ./adal:
-  -applicationId string
-        application id
-  -certificatePath string
-        path to pk12/PFC application certificate
-  -mode string
-        authentication mode (device, secret, cert, refresh) (default "device")
-  -resource string
-        resource for which the token is requested
-  -secret string
-        application secret
-  -tenantId string
-        tenant id
-  -tokenCachePath string
-        location of oath token cache (default "/home/cgc/.adal/accessToken.json")
-```
-
-Example acquire a token for `https://management.core.windows.net/` using device code flow:
-
-```
-adal -mode device \
-    -applicationId "APPLICATION_ID" \
-    -tenantId "TENANT_ID" \
-    -resource https://management.core.windows.net/
-
-```

-/*
-Package autorest implements an HTTP request pipeline suitable for use across multiple go-routines
-and provides the shared routines relied on by AutoRest (see https://github.com/Azure/autorest/)
-generated Go code.
-
-The package breaks sending and responding to HTTP requests into three phases: Preparing, Sending,
-and Responding. A typical pattern is:
-
-  req, err := Prepare(&http.Request{},
-    token.WithAuthorization())
-
-  resp, err := Send(req,
-    WithLogging(logger),
-    DoErrorIfStatusCode(http.StatusInternalServerError),
-    DoCloseIfError(),
-    DoRetryForAttempts(5, time.Second))
-
-  err = Respond(resp,
-    ByDiscardingBody(),
-    ByClosing())
-
-Each phase relies on decorators to modify and / or manage processing. Decorators may first modify
-and then pass the data along, pass the data first and then modify the result, or wrap themselves
-around passing the data (such as a logger might do). Decorators run in the order provided. For
-example, the following:
-
-  req, err := Prepare(&http.Request{},
-    WithBaseURL("https://microsoft.com/"),
-    WithPath("a"),
-    WithPath("b"),
-    WithPath("c"))
-
-will set the URL to:
-
-  https://microsoft.com/a/b/c
-
-Preparers and Responders may be shared and re-used (assuming the underlying decorators support
-sharing and re-use). Performant use is obtained by creating one or more Preparers and Responders
-shared among multiple go-routines, and a single Sender shared among multiple sending go-routines,
-all bound together by means of input / output channels.
-
-Decorators hold their passed state within a closure (such as the path components in the example
-above). Be careful to share Preparers and Responders only in a context where such held state
-applies. For example, it may not make sense to share a Preparer that applies a query string from a
-fixed set of values. Similarly, sharing a Responder that reads the response body into a passed
-struct (e.g., ByUnmarshallingJson) is likely incorrect.
-
-Lastly, the Swagger specification (https://swagger.io) that drives AutoRest
-(https://github.com/Azure/autorest/) precisely defines two date forms: date and date-time. The
-github.com/Azure/go-autorest/autorest/date package provides time.Time derivations to ensure
-correct parsing and formatting.
-
-Errors raised by autorest objects and methods will conform to the autorest.Error interface.
-
-See the included examples for more detail. For details on the suggested use of this package by
-generated clients, see the Client described below.

-Package spew implements a deep pretty printer for Go data structures to aid in
-debugging.
-
-A quick overview of the additional features spew provides over the built-in
-printing facilities for Go data types are as follows:
-
-	* Pointers are dereferenced and followed
-	* Circular data structures are detected and handled properly
-	* Custom Stringer/error interfaces are optionally invoked, including
-	  on unexported types
-	* Custom types which only implement the Stringer/error interfaces via
-	  a pointer receiver are optionally invoked when passing non-pointer
-	  variables
-	* Byte arrays and slices are dumped like the hexdump -C command which
-	  includes offsets, byte values in hex, and ASCII output (only when using
-	  Dump style)
-
-There are two different approaches spew allows for dumping Go data structures:
-
-	* Dump style which prints with newlines, customizable indentation,
-	  and additional debug information such as types and all pointer addresses
-	  used to indirect to the final value
-	* A custom Formatter interface that integrates cleanly with the standard fmt
-	  package and replaces %v, %+v, %#v, and %#+v to provide inline printing
-	  similar to the default %v while providing the additional functionality
-	  outlined above and passing unsupported format verbs such as %x and %q
-	  along to fmt
-
-Quick Start
-
-This section demonstrates how to quickly get started with spew.  See the
-sections below for further details on formatting and configuration options.
-
-To dump a variable with full newlines, indentation, type, and pointer
-information use Dump, Fdump, or Sdump:
-	spew.Dump(myVar1, myVar2, ...)
-	spew.Fdump(someWriter, myVar1, myVar2, ...)
-	str := spew.Sdump(myVar1, myVar2, ...)
-
-Alternatively, if you would prefer to use format strings with a compacted inline
-printing style, use the convenience wrappers Printf, Fprintf, etc with
-%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
-%#+v (adds types and pointer addresses):
-	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-	spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-
-Configuration Options
-
-Configuration of spew is handled by fields in the ConfigState type.  For
-convenience, all of the top-level functions use a global state available
-via the spew.Config global.
-
-It is also possible to create a ConfigState instance that provides methods
-equivalent to the top-level functions.  This allows concurrent configuration
-options.  See the ConfigState documentation for more details.
-
-The following configuration options are available:
-	* Indent
-		String to use for each indentation level for Dump functions.
-		It is a single space by default.  A popular alternative is "\t".
-
-	* MaxDepth
-		Maximum number of levels to descend into nested data structures.
-		There is no limit by default.
-
-	* DisableMethods
-		Disables invocation of error and Stringer interface methods.
-		Method invocation is enabled by default.
-
-	* DisablePointerMethods
-		Disables invocation of error and Stringer interface methods on types
-		which only accept pointer receivers from non-pointer variables.
-		Pointer method invocation is enabled by default.
-
-	* DisablePointerAddresses
-		DisablePointerAddresses specifies whether to disable the printing of
-		pointer addresses. This is useful when diffing data structures in tests.
-
-	* DisableCapacities
-		DisableCapacities specifies whether to disable the printing of
-		capacities for arrays, slices, maps and channels. This is useful when
-		diffing data structures in tests.
-
-	* ContinueOnMethod
-		Enables recursion into types after invoking error and Stringer interface
-		methods. Recursion after method invocation is disabled by default.
-
-	* SortKeys
-		Specifies map keys should be sorted before being printed. Use
-		this to have a more deterministic, diffable output.  Note that
-		only native types (bool, int, uint, floats, uintptr and string)
-		and types which implement error or Stringer interfaces are
-		supported with other types sorted according to the
-		reflect.Value.String() output which guarantees display
-		stability.  Natural map order is used by default.
-
-	* SpewKeys
-		Specifies that, as a last resort attempt, map keys should be
-		spewed to strings and sorted by those strings.  This is only
-		considered if SortKeys is true.
-
-Dump Usage
-
-Simply call spew.Dump with a list of variables you want to dump:
-
-	spew.Dump(myVar1, myVar2, ...)
-
-You may also call spew.Fdump if you would prefer to output to an arbitrary
-io.Writer.  For example, to dump to standard error:
-
-	spew.Fdump(os.Stderr, myVar1, myVar2, ...)
-
-A third option is to call spew.Sdump to get the formatted output as a string:
-
-	str := spew.Sdump(myVar1, myVar2, ...)
-
-Sample Dump Output
-
-See the Dump example for details on the setup of the types and variables being
-shown here.
-
-	(main.Foo) {
-	 unexportedField: (*main.Bar)(0xf84002e210)({
-	  flag: (main.Flag) flagTwo,
-	  data: (uintptr) <nil>
-	 }),
-	 ExportedField: (map[interface {}]interface {}) (len=1) {
-	  (string) (len=3) "one": (bool) true
-	 }
-	}
-
-Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
-command as shown.
-	([]uint8) (len=32 cap=32) {
-	 00000000  11 12 13 14 15 16 17 18  19 1a 1b 1c 1d 1e 1f 20  |............... |
-	 00000010  21 22 23 24 25 26 27 28  29 2a 2b 2c 2d 2e 2f 30  |!"#$%&'()*+,-./0|
-	 00000020  31 32                                             |12|
-	}
-
-Custom Formatter
-
-Spew provides a custom formatter that implements the fmt.Formatter interface
-so that it integrates cleanly with standard fmt package printing functions. The
-formatter is useful for inline printing of smaller data types similar to the
-standard %v format specifier.
-
-The custom formatter only responds to the %v (most compact), %+v (adds pointer
-addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
-combinations.  Any other verbs such as %x and %q will be sent to the the
-standard fmt package for formatting.  In addition, the custom formatter ignores
-the width and precision arguments (however they will still work on the format
-specifiers not handled by the custom formatter).
-
-Custom Formatter Usage
-
-The simplest way to make use of the spew custom formatter is to call one of the
-convenience functions such as spew.Printf, spew.Println, or spew.Printf.  The
-functions have syntax you are most likely already familiar with:
-
-	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-	spew.Println(myVar, myVar2)
-	spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-
-See the Index for the full list convenience functions.
-
-Sample Formatter Output
-
-Double pointer to a uint8:
-	  %v: <**>5
-	 %+v: <**>(0xf8400420d0->0xf8400420c8)5
-	 %#v: (**uint8)5
-	%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
-
-Pointer to circular struct with a uint8 field and a pointer to itself:
-	  %v: <*>{1 <*><shown>}
-	 %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
-	 %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
-	%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
-
-See the Printf example for details on the setup of variables being shown
-here.
-
-Errors
-
-Since it is possible for custom Stringer/error interfaces to panic, spew
-detects them and handles them internally by printing the panic information
-inline with the output.  Since spew is intended to provide deep pretty printing
-capabilities on structures, it intentionally does not return any errors.

-## Migration Guide from v2 -> v3
-
-Version 3 adds several new, frequently requested features.  To do so, it introduces a few breaking changes.  We've worked to keep these as minimal as possible.  This guide explains the breaking changes and how you can quickly update your code.
-
-### `Token.Claims` is now an interface type
-
-The most requested feature from the 2.0 verison of this library was the ability to provide a custom type to the JSON parser for claims. This was implemented by introducing a new interface, `Claims`, to replace `map[string]interface{}`.  We also included two concrete implementations of `Claims`: `MapClaims` and `StandardClaims`.
-
-`MapClaims` is an alias for `map[string]interface{}` with built in validation behavior.  It is the default claims type when using `Parse`.  The usage is unchanged except you must type cast the claims property.
-
-The old example for parsing a token looked like this..
-
-```go
-	if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil {
-		fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"])
-	}
-```
-
-is now directly mapped to...
-
-```go
-	if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil {
-		claims := token.Claims.(jwt.MapClaims)
-		fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"])
-	}
-```
-
-`StandardClaims` is designed to be embedded in your custom type.  You can supply a custom claims type with the new `ParseWithClaims` function.  Here's an example of using a custom claims type.
-
-```go
-	type MyCustomClaims struct {
-		User string
-		*StandardClaims
-	}
-	
-	if token, err := jwt.ParseWithClaims(tokenString, &MyCustomClaims{}, keyLookupFunc); err == nil {
-		claims := token.Claims.(*MyCustomClaims)
-		fmt.Printf("Token for user %v expires %v", claims.User, claims.StandardClaims.ExpiresAt)
-	}
-```
-
-### `ParseFromRequest` has been moved
-
-To keep this library focused on the tokens without becoming overburdened with complex request processing logic, `ParseFromRequest` and its new companion `ParseFromRequestWithClaims` have been moved to a subpackage, `request`.  The method signatues have also been augmented to receive a new argument: `Extractor`.
-
-`Extractors` do the work of picking the token string out of a request.  The interface is simple and composable.
-
-This simple parsing example:
-
-```go
-	if token, err := jwt.ParseFromRequest(tokenString, req, keyLookupFunc); err == nil {
-		fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"])
-	}
-```
-
-is directly mapped to:
-
-```go
-	if token, err := request.ParseFromRequest(tokenString, request.OAuth2Extractor, req, keyLookupFunc); err == nil {
-		fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"])
-	}
-```
-
-There are several concrete `Extractor` types provided for your convenience:
-
-* `HeaderExtractor` will search a list of headers until one contains content.
-* `ArgumentExtractor` will search a list of keys in request query and form arguments until one contains content.
-* `MultiExtractor` will try a list of `Extractors` in order until one returns content.
-* `AuthorizationHeaderExtractor` will look in the `Authorization` header for a `Bearer` token.
-* `OAuth2Extractor` searches the places an OAuth2 token would be specified (per the spec): `Authorization` header and `access_token` argument
-* `PostExtractionFilter` wraps an `Extractor`, allowing you to process the content before it's parsed.  A simple example is stripping the `Bearer ` text from a header
-
-
-### RSA signing methods no longer accept `[]byte` keys
-
-Due to a [critical vulnerability](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/), we've decided the convenience of accepting `[]byte` instead of `rsa.PublicKey` or `rsa.PrivateKey` isn't worth the risk of misuse.
-
-To replace this behavior, we've added two helper methods: `ParseRSAPrivateKeyFromPEM(key []byte) (*rsa.PrivateKey, error)` and `ParseRSAPublicKeyFromPEM(key []byte) (*rsa.PublicKey, error)`.  These are just simple helpers for unpacking PEM encoded PKCS1 and PKCS8 keys. If your keys are encoded any other way, all you need to do is convert them to the `crypto/rsa` package's types.
-
-```go 
-	func keyLookupFunc(*Token) (interface{}, error) {
-		// Don't forget to validate the alg is what you expect:
-		if _, ok := token.Method.(*jwt.SigningMethodRSA); !ok {
-			return nil, fmt.Errorf("Unexpected signing method: %v", token.Header["alg"])
-		}
-		
-		// Look up key 
-		key, err := lookupPublicKey(token.Header["kid"])
-		if err != nil {
-			return nil, err
-		}
-		
-		// Unpack key from PEM encoded PKCS8
-		return jwt.ParseRSAPublicKeyFromPEM(key)
-	}
-```

We've tried to break as few things as possible, so there should just be a few type signature changes.  A full list of breaking changes is available in `VERSION_HISTORY.md`.

-**NOTICE:** A vulnerability in JWT was [recently published](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/).  As this library doesn't force users to validate the `alg` is what they expected, it's possible your usage is effected.  There will be an update soon to remedy this, and it will likey require backwards-incompatible changes to the API.  In the short term, please make sure your implementation verifies the `alg` is what you expect.
-
-
-## What the heck is a JWT?
-
-JWT.io has [a great introduction](https://jwt.io/introduction) to JSON Web Tokens.
-
-In short, it's a signed JSON object that does something useful (for example, authentication).  It's commonly used for `Bearer` tokens in Oauth 2.  A token is made of three parts, separated by `.`'s.  The first two parts are JSON objects, that have been [base64url](http://tools.ietf.org/html/rfc4648) encoded.  The last part is the signature, encoded the same way.
-
-The first part is called the header.  It contains the necessary information for verifying the last part, the signature.  For example, which encryption method was used for signing and what key was used.
-
-The part in the middle is the interesting bit.  It's called the Claims and contains the actual stuff you care about.  Refer to [the RFC](http://self-issued.info/docs/draft-jones-json-web-token.html) for information about reserved keys and the proper way to add your own.
-
-## What's in the box?
-
-This library supports the parsing and verification as well as the generation and signing of JWTs.  Current supported signing algorithms are HMAC SHA, RSA, RSA-PSS, and ECDSA, though hooks are present for adding your own.
-
-## Examples
-
-See [the project documentation](https://godoc.org/github.com/dgrijalva/jwt-go) for examples of usage:
-
-* [Simple example of parsing and validating a token](https://godoc.org/github.com/dgrijalva/jwt-go#example-Parse--Hmac)
-* [Simple example of building and signing a token](https://godoc.org/github.com/dgrijalva/jwt-go#example-New--Hmac)
-* [Directory of Examples](https://godoc.org/github.com/dgrijalva/jwt-go#pkg-examples)
-
-## Extensions
-
-This library publishes all the necessary components for adding your own signing methods.  Simply implement the `SigningMethod` interface and register a factory method using `RegisterSigningMethod`.  
-
-Here's an example of an extension that integrates with the Google App Engine signing tools: https://github.com/someone1/gcp-jwt-go
-
-## Compliance
-
-This library was last reviewed to comply with [RTF 7519](http://www.rfc-editor.org/info/rfc7519) dated May 2015 with a few notable differences: 
-
-* In order to protect against accidental use of [Unsecured JWTs](http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html#UnsecuredJWT), tokens using `alg=none` will only be accepted if the constant `jwt.UnsafeAllowNoneSignatureType` is provided as the key.
-
-## Project Status & Versioning
-
-This library is considered production ready.  Feedback and feature requests are appreciated.  The API should be considered stable.  There should be very few backwards-incompatible changes outside of major version updates (and only with good reason).
-
-This project uses [Semantic Versioning 2.0.0](http://semver.org).  Accepted pull requests will land on `master`.  Periodically, versions will be tagged from `master`.  You can find all the releases on [the project releases page](https://github.com/dgrijalva/jwt-go/releases).
-
-While we try to make it obvious when we make breaking changes, there isn't a great mechanism for pushing announcements out to users.  You may want to use this alternative package include: `gopkg.in/dgrijalva/jwt-go.v2`.  It will do the right thing WRT semantic versioning.
-
-## Usage Tips
-
-### Signing vs Encryption
-
-A token is simply a JSON object that is signed by its author. this tells you exactly two things about the data:
-
-* The author of the token was in the possession of the signing secret
-* The data has not been modified since it was signed
-
-It's important to know that JWT does not provide encryption, which means anyone who has access to the token can read its contents. If you need to protect (encrypt) the data, there is a companion spec, `JWE`, that provides this functionality. JWE is currently outside the scope of this library.
-
-### Choosing a Signing Method
-
-There are several signing methods available, and you should probably take the time to learn about the various options before choosing one.  The principal design decision is most likely going to be symmetric vs asymmetric.
-
-Symmetric signing methods, such as HSA, use only a single secret. This is probably the simplest signing method to use since any `[]byte` can be used as a valid secret. They are also slightly computationally faster to use, though this rarely is enough to matter. Symmetric signing methods work the best when both producers and consumers of tokens are trusted, or even the same system. Since the same secret is used to both sign and validate tokens, you can't easily distribute the key for validation.
-
-Asymmetric signing methods, such as RSA, use different keys for signing and verifying tokens. This makes it possible to produce tokens with a private key, and allow any consumer to access the public key for verification.
-
-### JWT and OAuth
-
-It's worth mentioning that OAuth and JWT are not the same thing. A JWT token is simply a signed JSON object. It can be used anywhere such a thing is useful. There is some confusion, though, as JWT is the most common type of bearer token used in OAuth2 authentication.
-
-Without going too far down the rabbit hole, here's a description of the interaction of these technologies:
-
-* OAuth is a protocol for allowing an identity provider to be separate from the service a user is logging in to.  For example, whenever you use Facebook to log into a different service (Yelp, Spotify, etc), you are using OAuth.
-* OAuth defines several options for passing around authentication data. One popular method is called a "bearer token". A bearer token is simply a string that _should_ only be held by an authenticated user. Thus, simply presenting this token proves your identity. You can probably derive from here why a JWT might make a good bearer token.
-* Because bearer tokens are used for authentication, it's important they're kept secret. This is why transactions that use bearer tokens typically happen over SSL.
- 
-## More
-
-Documentation can be found [on godoc.org](http://godoc.org/github.com/dgrijalva/jwt-go).
-
-The command line utility included in this project (cmd/jwt) provides a straightforward example of token creation and parsing as well as a useful tool for debugging your own integration.  You'll also find several implementation examples in to documentation.

-## `jwt-go` Version History
-
-#### 3.0.0
-
-* **Compatibility Breaking Changes**: See MIGRATION_GUIDE.md for tips on updating your code
-	* Dropped support for `[]byte` keys when using RSA signing methods.  This convenience feature could contribute to security vulnerabilities involving mismatched key types with signing methods.
-	* `ParseFromRequest` has been moved to `request` subpackage and usage has changed
-	* The `Claims` property on `Token` is now type `Claims` instead of `map[string]interface{}`.  The default value is type `MapClaims`, which is an alias to `map[string]interface{}`.  This makes it possible to use a custom type when decoding claims.
-* Other Additions and Changes
-	* Added `Claims` interface type to allow users to decode the claims into a custom type
-	* Added `ParseWithClaims`, which takes a third argument of type `Claims`.  Use this function instead of `Parse` if you have a custom type you'd like to decode into.
-	* Dramatically improved the functionality and flexibility of `ParseFromRequest`, which is now in the `request` subpackage
-	* Added `ParseFromRequestWithClaims` which is the `FromRequest` equivalent of `ParseWithClaims`
-	* Added new interface type `Extractor`, which is used for extracting JWT strings from http requests.  Used with `ParseFromRequest` and `ParseFromRequestWithClaims`.
-	* Added several new, more specific, validation errors to error type bitmask
-	* Moved examples from README to executable example files
-	* Signing method registry is now thread safe
-	* Added new property to `ValidationError`, which contains the raw error returned by calls made by parse/verify (such as those returned by keyfunc or json parser)
-
-#### 2.7.0
-
-This will likely be the last backwards compatible release before 3.0.0, excluding essential bug fixes.
-
-* Added new option `-show` to the `jwt` command that will just output the decoded token without verifying
-* Error text for expired tokens includes how long it's been expired
-* Fixed incorrect error returned from `ParseRSAPublicKeyFromPEM`
-* Documentation updates
-
-#### 2.6.0
-
-* Exposed inner error within ValidationError
-* Fixed validation errors when using UseJSONNumber flag
-* Added several unit tests
-
-#### 2.5.0
-
-* Added support for signing method none.  You shouldn't use this.  The API tries to make this clear.
-* Updated/fixed some documentation
-* Added more helpful error message when trying to parse tokens that begin with `BEARER `
-
-#### 2.4.0
-
-* Added new type, Parser, to allow for configuration of various parsing parameters
-	* You can now specify a list of valid signing methods.  Anything outside this set will be rejected.
-	* You can now opt to use the `json.Number` type instead of `float64` when parsing token JSON
-* Added support for [Travis CI](https://travis-ci.org/dgrijalva/jwt-go)
-* Fixed some bugs with ECDSA parsing
-
-#### 2.3.0
-
-* Added support for ECDSA signing methods
-* Added support for RSA PSS signing methods (requires go v1.4)
-
-#### 2.2.0
-
-* Gracefully handle a `nil` `Keyfunc` being passed to `Parse`.  Result will now be the parsed token and an error, instead of a panic.
-
-#### 2.1.0
-
-Backwards compatible API change that was missed in 2.0.0.
-
-* The `SignedString` method on `Token` now takes `interface{}` instead of `[]byte`
-
-#### 2.0.0
-
-There were two major reasons for breaking backwards compatibility with this update.  The first was a refactor required to expand the width of the RSA and HMAC-SHA signing implementations.  There will likely be no required code changes to support this change.
-
-The second update, while unfortunately requiring a small change in integration, is required to open up this library to other signing methods.  Not all keys used for all signing methods have a single standard on-disk representation.  Requiring `[]byte` as the type for all keys proved too limiting.  Additionally, this implementation allows for pre-parsed tokens to be reused, which might matter in an application that parses a high volume of tokens with a small set of keys.  Backwards compatibilty has been maintained for passing `[]byte` to the RSA signing methods, but they will also accept `*rsa.PublicKey` and `*rsa.PrivateKey`.
-
-It is likely the only integration change required here will be to change `func(t *jwt.Token) ([]byte, error)` to `func(t *jwt.Token) (interface{}, error)` when calling `Parse`.
-
-* **Compatibility Breaking Changes**
-	* `SigningMethodHS256` is now `*SigningMethodHMAC` instead of `type struct`
-	* `SigningMethodRS256` is now `*SigningMethodRSA` instead of `type struct`
-	* `KeyFunc` now returns `interface{}` instead of `[]byte`
-	* `SigningMethod.Sign` now takes `interface{}` instead of `[]byte` for the key
-	* `SigningMethod.Verify` now takes `interface{}` instead of `[]byte` for the key
-* Renamed type `SigningMethodHS256` to `SigningMethodHMAC`.  Specific sizes are now just instances of this type.
-    * Added public package global `SigningMethodHS256`
-    * Added public package global `SigningMethodHS384`
-    * Added public package global `SigningMethodHS512`
-* Renamed type `SigningMethodRS256` to `SigningMethodRSA`.  Specific sizes are now just instances of this type.
-    * Added public package global `SigningMethodRS256`
-    * Added public package global `SigningMethodRS384`
-    * Added public package global `SigningMethodRS512`
-* Moved sample private key for HMAC tests from an inline value to a file on disk.  Value is unchanged.
-* Refactored the RSA implementation to be easier to read
-* Exposed helper methods `ParseRSAPrivateKeyFromPEM` and `ParseRSAPublicKeyFromPEM`
-
-#### 1.0.2
-
-* Fixed bug in parsing public keys from certificates
-* Added more tests around the parsing of keys for RS256
-* Code refactoring in RS256 implementation.  No functional changes
-
-#### 1.0.1
-
-* Fixed panic if RS256 signing method was passed an invalid key
-
-#### 1.0.0
-
-* First versioned release
-* API stabilized
-* Supports creating, signing, parsing, and validating JWT tokens
