Private key encryption by Passphrase

[Amarpal Singh]

Does this encryption need a symmetric key. Who provides that? Can that be
chosen by the user?

On page 92 of Barrettt & Richards book "SSH, The Secure Shell, The
Definitive Guide" I see that OpenSSH doesn't support all the Ciphers. Do you
have a list of Ciphers supported by OpenSSH3.1 for encryption?

Thanks
Amarpal.

different modes of 3des, depending on the protocol.

it supports all REQUIRED ciphers and many more
