DES encoding/decoding through openssl library

Copy/pastin results and bash line codes is really boring and tedious while python can access openssl and we can automate the whole thing!

http://launchpad.net/pyopenssl -> python-openssl package under debian

At first, the target is to have a standalone script that automates the whole thing.

Then, we could expand scriptim to use it from within the command line (plugin system?)
