% man ssh
/cipher

-c cipher_spec
             Selects the cipher specification for encrypting the session.

             Protocol version 1 allows specification of a single cipher.  The supported values are
             “3des”, “blowfish”, and “des”.  3des (triple-des) is an encrypt-decrypt-encrypt
             triple with three different keys.  It is believed to be secure.  blowfish is a fast
             block cipher; it appears very secure and is much faster than 3des.  des is only sup&#8208;
             ported in the ssh client for interoperability with legacy protocol 1 implementations
             that do not support the 3des cipher.  Its use is strongly discouraged due to crypto&#8208;
             graphic weaknesses.  The default is “3des”.

             For protocol version 2, cipher_spec is a comma-separated list of ciphers listed in
             order of preference.  See the Ciphers keyword in ssh_config(5) for more information.
