KeyType
The type of a cryptographic key.
@ EC
Elliptic Curve key (e.g. for ECDSA), supports sign/verify operations.
@ RSA
RSA key, supports sign/verify and encrypt/decrypt operations.
@ AES
AES key, supports encrypt/decrypt operations.
@ NONE
Unknown or unsupported key type.
@ HMAC
HMAC key, supports sign/verify operations.
KeyIdType
The type of KeyId component in a key name.
@ RANDOM
Use a 64-bit random number as key id.
@ USER_SPECIFIED
User-specified key id.
@ SHA256
Use the SHA-256 hash of the public key as key id.
