kaskpass is a ssh-askpass replacement for Kde. In add, it allows use of kwalletd to manage your passphrase(s).

See ssh man pages for more information about ssh system, ssh keys, ssh-agent and ssh-askpass.

It is written in ruby. It depends of ruby interpreter, libkorundum and kwallet. It is packaged to be installed in /usr/bin, but you can easily use it from your home directory.
