Interface SigningMethod

signing_method.go:14–18

SigningMethod can be used add new methods for signing or verifying tokens. It takes a decoded signature as an input in the Verify function and produces a signature in Sign. The signature is then usually base64 encoded as part of a JWT.

// signature in Sign. The signature is then usually base64 encoded as part of a
// JWT.
type SigningMethod interface {
	Verify(signingString string, sig []byte, key any) error // Returns nil if signature is valid
	Sign(signingString string, key any) ([]byte, error)     // Returns signature or error
	Alg() string                                            // returns the alg identifier for this method (example: 'HS256')
}

// RegisterSigningMethod registers the "alg" name and a factory function for signing method.
// This is typically done during init() in the method's implementation
