Insecure Cipher Suite
- IANA name:
- Hex code:
- 0xC0, 0x5B
- TLS Version(s):
- Transport Layer Security (TLS)
- Key Exchange:
- Diffie-Hellman (DH)
- Anonymous (anon)
- ARIA with 256bit key in Galois/Counter mode (ARIA 256 GCM)
- Secure Hash Algorithm 384 (SHA384)
- Included in RFC:
Diffie-Hellman key exchanges not using ephemeral keys do not support Perfect Forward Secrecy (PFS) which is recommended, so attackers cannot decrypt the whole communication stream.
Anonymous key exchanges are generally vulnerable to Man in the Middle attacks.
