Types ¶

type Method ¶

type Method struct {
	PrivateKey *rsa.PrivateKey
	PublicKey  *rsa.PublicKey
	HashFunc   func() hash.Hash
	Hash       crypto.Hash
	Name       string
	// contains filtered or unexported fields
}

func New ¶

func New(algorithm string, privateKey *rsa.PrivateKey, publicKey *rsa.PublicKey) (*Method, error)

func NewFromPublicKey ¶

func NewFromPublicKey(publicKey *rsa.PublicKey) (*Method, error)

NewFromPublicKey constructs a verifying Method from an RSA public key by heuristically selecting a JOSE RSA algorithm based on modulus size.

Heuristics (PKCS#1 v1.5):

n bits >= 4096 -> RS512
n bits >= 3072 -> RS384
otherwise -> RS256

Note: The choice between PKCS#1 v1.5 (RS*) and PSS (PS*) cannot be inferred from the key alone. This helper defaults to RS* for maximum interoperability.

func (*Method) GetName ¶

func (m *Method) GetName() string

func (*Method) Sign ¶

func (m *Method) Sign(message []byte) ([]byte, error)

func (*Method) Verify ¶

func (m *Method) Verify(message []byte, signature []byte) error
