Insecure Cipher Suite
- IANA name:
- GnuTLS name:
- Hex code:
- 0xC0, 0x84
- TLS Version(s):
- Transport Layer Security (TLS)
- Key Exchange:
- Diffie-Hellman (DH)
- Anonymous (anon)
- CAMELLIA with 128bit key in Galois/Counter mode (CAMELLIA 128 GCM)
- Secure Hash Algorithm 256 (SHA256)
- 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.
