Constants

const TokenHeaderKeyPrefix = "BEARER "

TokenHeaderKeyPrefix is a token prefix regarding RFCXXX.

Variables

var (
	// ErrWrongSignatureAlgorithm is for unsupported signature algorithm.
	ErrWrongSignatureAlgorithm = errors.New("Unsupported signature algorithm")
	// ErrEmptyToken is when token is empty.
	ErrEmptyToken = errors.New("Token is empty")
	// ErrTokenInvalid is when token is invalid.
	ErrTokenInvalid = errors.New("Token is invalid")
)

var StrToTokenSignAlg = map[string]TokenSignatureAlgorithm{
	"es256": TokenSignatureAlgorithmES256,
	"rs256": TokenSignatureAlgorithmRS256,
	"auto":  TokenSignatureAlgorithmAuto}

StrToTokenSignAlg maps string token service algorithm names to values.

var TimeFunc = time.Now

TimeFunc provides the current time when parsing token to validate "exp" claim (expiration time). You can override it to use another time value. This is useful for testing or if your server uses a time zone different from your tokens'.

Functions
