Parameters

cipher-string

Specifies the ciphers allowed by OpenSSH version 2 to use in SSH communication. The order of cipher suites is important. The server compares its list to the client's list in order of preference. The first cipher suite in the client's list is chosen when it is also supported by the server.

The cipher suites in the following list are supported and all are default values. You can change the preference order of cipher suites.
