4. A128KW: AES Key Wrap with default initial value using 128-bit key
5. A192KW: AES Key Wrap with default initial value using 192-bit key
6. A256KW: AES Key Wrap with default initial value using 256-bit key
7. A128GCMKW: Key wrapping with AES GCM using 128-bit key
8. A192GCMKW: Key wrapping with AES GCM using 192-bit key
9. A256GCMKW: Key wrapping with AES GCM using 256-bit key
10. ECDH-ES: In the Direct Key Agreement mode
11. ECDH-ES+A128KW: using Concat KDF and CEK wrapped with A128KW

2. A192CBC-HS384
3. A256CBC-HS512
4. A128GCM
5. A192GCM
6. A256GCM
Current available algorithms for ``zip``:
1. DEF
Algorithms for JWK
