HS256_64

@Serializable(with = CoseAlgorithmSerializer::class)
data object HS256_64 : CoseAlgorithm.MAC

SHA-265 with truncated output. Beware: This maps to HMAC.SHA256, but HMAC.SHA256 maps to HS256!

Functions

fun SpecializedDataIntegrityAlgorithm.toCoseAlgorithm(): KmmResult<CoseAlgorithm.DataIntegrity>
fun SpecializedMessageAuthenticationCode.toCoseAlgorithm(): KmmResult<CoseAlgorithm.MAC>

Tries to find a matching COSE algorithm. Note that COSE imposes curve restrictions on ECDSA based on the digest.
