Protocol 2 provides additional mechanisms for confidentiality

(the traffic is encrypted using 3DES, blowfish, cast128 or arcfour)

(the traffic is encrypted using 3DES, Blowfish, CAST128 or Arcfour)

and integrity (hmac-sha1, hmac-md5).

Note that protocol 1 lacks a strong mechanism for ensuring the

integrity of the connection.

Line 342

(triple-des) is an encrypt-decrypt-encrypt triple with three different keys.

It is presumably more secure than the

.Ar des

cipher which is no longer supported in ssh.

cipher which is no longer supported in

.Nm ssh .

.Ar blowfish

is a fast block cipher, it appears very secure and is much faster than

.Ar 3des .

Additionally, for protocol version 2 a comma-separated list of ciphers can

be specified in order of preference. Protocol version 2 supports

3DES, Blowfish and CAST128 in CBC mode and Arcfour.

Multiple ciphers must be comma-separated.

The default is
