jwt-go Version History

3.0.0

• 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.
• Added Claims interface type to allow users to decode the claims into a custom type
• 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.
• 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.

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
• Supports RS256 and HS256 signing methods
