Synopsis

SSL/TLS Weak Key Exchange Supported

Description

The remote host supports SSL/TLS key exchanges that are cryptographically weaker than recommended. Key exchanges must be recommended by IANA and should provide at least 224 bits of security, which translates to a minimum key size of 2048 bits for Diffie Hellman and RSA key exchanges.

Solution

Reconfigure the affected application, if possible to avoid the use of weak key exchange.
