Functions ¶
func Algorithms ¶
func Algorithms() map[int]COSEAlgorithm
Algorithms returns the implemented COSE algorithms by COSE algorithm value.
Types ¶
type COSEAlgorithm ¶
type COSEAlgorithm interface {
// Value returns the COSE algorithm value for the algorithm.
Value() int
// CheckKeyType checks that the public key is the correct type for the
// algorithm, returning an error if not.
CheckKeyType(key any) error
// Verify uses the public key to perform a verification of the message data
// using sig, returning an error if the key type is incorrect or the
// verification failed.
Verify(key any, message, sig []byte) error
}
COSEAlgorithm implementers provide functions for using public keys to verify data signed using standard COSE algorithms.
See the algorithm definitions: https://www.iana.org/assignments/cose/cose.xhtml#algorithms
type ES256 ¶
type ES256 struct{}
ES256 uses ECDSA keys to verify ASN.1 signatures of SHA256 hashes.
func (*ES256) CheckKeyType ¶
type EdDSA ¶
type EdDSA struct{}
EdDSA uses Ed25519 keys to verify signatures.
func (*EdDSA) CheckKeyType ¶
type RS256 ¶
type RS256 struct{}
RS256 uses RSA keys to verify PKCS#1 v1.5 signatures generated using SHA256.
func (*RS256) CheckKeyType ¶
