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.
NULL Encryption:
This cipher suite uses no encryption at all. Hence, it does not provide confidentiality protection.
