Functions ¶
func DecodeSignature ¶
DecodeSignature decodes (r, s) from a signature bytes using the method specified by RFC 8152 section 8.1.
func EncodeSignature ¶
EncodeSignature encodes (r, s) into a signature bytes using the method specified by RFC 8152 section 8.1.
func GenerateKey ¶
GenerateKey generates a new Key with given algorithm for ECDSA. alg is one of the iana.AlgorithmES* constants.
func KeyFromPrivate ¶
func KeyFromPrivate(pk *goecdsa.PrivateKey) (key.Key, error)
KeyFromPrivate returns a private Key with given ecdsa.PrivateKey.
func KeyFromPublic ¶
KeyFromPublic returns a public Key with given ecdsa.PublicKey.
func KeyToPrivate ¶ added in v0.5.0
func KeyToPrivate(k key.Key) (*goecdsa.PrivateKey, error)
KeyToPrivate returns a ecdsa.PrivateKey for the given Key.
func KeyToPublic ¶ added in v0.5.0
KeyToPublic returns a ecdsa.PublicKey for the given key.Key.
func NewVerifier ¶
NewVerifier creates a key.Verifier for the given public key.
func ToCompressedKey ¶ added in v0.5.0
ToCompressedKey converts the given key to a compressed Key. It can be used in Recipient.
