[Solved] Encrypt files?

[ayu]

I have a file with some private data in that I want to have tight security on, and I mean TIGHT. I don't want any weak encryption that uses a weak algorithm. Of course I have to be able to decrypt it as well.

Anyone know of a small application that can do this for me?


EDIT: Found a encrypt function built into Ubuntu, can't figure out how to use it though XD

EDIT 2: Thuggy introduced me to truecrypt, works like a charm =) thanks mate
