Pradeepto, specially for you ..
$ sudo apt-get install kgpg gnupg

that will install KDE frontend for GNUPG and gnupg package. KDE client you can manage but here's how to do it with gpg command line interface.

1) Generate key pairs.
$ gpg --gen-key
and follow all the instructions.

2) Visit MIT PGP public keyserver and submit your public keys there. This enables your friends to verify messages signed by you against the public keys stored on mit's pgp server.

This is how to generate an ASCII armoured public key that can be submitted to the mit keyserver or sent to your friends so that they can add your public key in their keyring.

3) Now next time you use mutt, you can use the [P] key to use gpg specific options like signing your email, or encrypting it perhaps.

4) And this is how you can add your friend's public keys if they happen to send you one.
$ gpg --import pub-key-file.asc

And of course you can always use your KGPG program

Prasanta asked me a week back,

How to identify if a given shell server is running on a 32bit or 64bit hardware?

We pondered over it and thought of all possible options, $ arch, /proc/cpuinfo, etc.. but yesterday i came across this nifty utility $ lshw.. Try it now if you can.. trust me you'll love it.. And for prasanta, this is how i identified it is 32bit computer.
