- IANA name:
- TLS_ECDH_ECDSA_WITH_AES_256_GCM_SHA384
- Hex code:
- 0xC0, 0x2E
- TLS Version(s):
- TLS1.2, TLS1.3
- Protocol:
- Transport Layer Security (TLS)
- Key Exchange:
- Elliptic Curve Diffie-Hellman (ECDH)
- Authentication:
- Elliptic Curve Digital Signature Algorithm (ECDSA)
- Encryption:
- AEAD Advanced Encryption Standard with 256bit key in Galois/Counter mode (AES 256 GCM)
- Hash:
- Secure Hash Algorithm 384 (SHA384)
- Included in RFC:
- Machine-readable:
- application/json
Non-ephemeral Key Exchange:
This key exchange algorithm does not support Perfect Forward Secrecy (PFS) which is recommended, so attackers cannot decrypt the complete communication stream.
