/**
 * A {@code ProtectedJwt} is a {@link Jwt} that is integrity protected via a cryptographic algorithm that produces

 *
 * Cryptographic Digest
 * This interface extends DigestSupplier to make available the {@code ProtectedJwt}'s associated cryptographic
 * digest:
 * 
 *     If the JWT is a {@link Jws}, {@link #getDigest() getDigest() } returns the JWS signature.
 *     If the JWT is a {@link Jwe}, {@link #getDigest() getDigest() } returns the AAD Authentication Tag.
 * 
 *
 * @param  the type of the JWT protected header
 * @param  the type of the JWT payload, either a content byte array or a {@link Claims} instance.
 * @since 0.12.0
