Insecure Cipher Suite

IANA name:

TLS_NULL_WITH_NULL_NULL

Hex code:

0x00, 0x00

TLS Version(s):

TLS1.0, TLS1.1, TLS1.2, TLS1.3

---

Protocol:

Transport Layer Security (TLS)

Key Exchange:

NULL Key exchange (NULL)

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:

Null Authentication (NULL)

NULL Authentication:

This cipher suite uses no authentication at all. Hence, it is not providing integrity.

Encryption:

NULL Encryption (NULL)

NULL Encryption:

This cipher suite uses no encryption at all. Hence, it is not providing confidentiality.

Hash:

HMAC NULL Hash (NULL)
