undo ssh server key-exchange The device supports the insecure dh_group1_sha1, dh_group14_sha1, and dh_group_exchange_sha1 key exchange algorithms only when the weak-encryption-algorithm plug-in is installed. For details about the plug-in, see section Weak-Encryption-Algorithm Plug-in Manag...
weak key exchange method supported by Server. The criteria of a weak KEX method is as follows: The SSL/TLS server supports key exchanges that are cryptographically weaker than recommended. Key exchanges should provide at least 112 bits of security, which translates to a minimum key size of ...
