When I need to email someone something sensitive I generally use 7za(1) which uses 256-bit AES*. If you install the p7zip package you;ll get a zip(1)-like wrapper for 7za which you might find more intuitive. And depending on your desktop environment you may be able to encyrpt/decrypt using 7za by right-clicking on files/directories in the file manager (works in Nautilus'; select Compress.. >>".7z" & "Other Options" for encrypting). Just wanted to mention here that, if you're working with email, a few GUI packages can make the process a little simpler. I've only been implementing these GUI tools on OpenBSD, and I'll admit they've been a little 'crashy', but I'm sure on Linux, where they've got a userbase large enough to facilitate beta testing quickly, these issues should be worked out. I know at least one person who is having no real problems with _Thunderbird_, with appropriate encryption plugins installed; _claws_, or _claws-mail_ is the one that I've been using lately. Both of these mail clients will help you with generating a PGP key (through GPG, unless otherwise specified), as well as auto-signing your messages when you're emailing, checking digital signatures on signed messages coming in to your account, encrypting by default to recipients that email you encrypted content, and auto-decrypting messages encrypted to you. Not sure about symmetric encryption through those clients, but once you've got them installed, along with GPG, you'll have gpg available for symmetric encryption at the command line, if you so desire. I won't get into the encryption algorithm 'holy wars' at this time. ;) You could also use openssl for encrypting files but it's awkward and apparently regularly appearing bugs...
