Insecure Cipher Suite

IANA name:

TLS_DH_anon_WITH_ARIA_256_GCM_SHA384

Hex code:

0xC0, 0x5B

TLS Version(s):

TLS1.2, TLS1.3

---

Protocol:

Transport Layer Security (TLS)

Key Exchange:

Diffie-Hellman (DH)

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.

Authentication:

Anonymous (anon)

Anonymous key exchange:

Anonymous key exchanges are generally vulnerable to Man in the Middle attacks.

Encryption:

AEAD ARIA with 256bit key in Galois/Counter mode (ARIA 256 GCM)

Hash:

Secure Hash Algorithm 384 (SHA384)
