Functions

func BuildDIDKeyByKeyType

func BuildDIDKeyByKeyType(pubKeyBytes []byte, keyType kms.KeyType) (string, error)

BuildDIDKeyByKeyType creates a did key for pubKeyBytes based on the kms keyType.

func EncryptionPubKeyFromDIDKey

func EncryptionPubKeyFromDIDKey(didKey string) (*cryptoapi.PublicKey, error)

EncryptionPubKeyFromDIDKey parses the did:key DID and returns the key's raw value. note: for NIST P ECDSA keys, the raw value does not have the compression point.

In order to use elliptic.Unmarshal() with the raw value, the uncompressed point ([]byte{4}) must be prepended.
