alg?: "A128CBC" | "A192CBC" | "A256CBC" | "A128CTR" | "A192CTR" | "A256CTR" | "A128GCM" | "A192GCM" | "A256GCM" | "HS256" | "HS384" | "HS512"The algorithm intended for use with the key. Used with symmetric signing (e.g., HMAC HS256, etc.) and symmetric encryption (e.g., A256GCM, etc.) algorithms.
The "k" (key value) parameter contains the value of the symmetric (or other single-valued) key. It is represented as the base64url encoding of the octet sequence containing the key value.
Key type oct (Octet Sequence) is defined for symmetric encryption and symmetric signature algorithms.
Parameters used with "oct" (octet sequence) private keys.
