.Ar 3des |
|
(triple-des) is an encrypt-decrypt-encrypt triple with three different keys. |
|
It is believed to be secure. |
|
.Ar blowfish |
|
is a fast block cipher; it appears very secure and is much faster than |

|
.Ar des |
|
is only supported in the |

|
client for interoperability with legacy protocol 1 implementations |
|
that do not support the |

cipher. |
|
Its use is strongly discouraged due to cryptographic weaknesses. |
