Simple Password Encrypted Files w/ GnuPG

It uses GPG for symmetric encryption as per TFA.

(Non-security-researcher suggestion follows, take with a grain of salt): Note that the default encryption algo used with the -c option is usually CAST5. Though there haven't been any successful attacks against it yet, in today's world of the NSA storing communications indefinitely you might want to consider using AES256 instead of CAST5 to (semi) future-proof your encrypted files. You can do that by adding the following line to ~/.gnupg/gpg.conf:

    personal-cipher-preferences aes256 3des

If you structure the file, say, passswords, appropriately, or even very loosely (one record per line), you can write a bash script or function to query the file. More useful if you've got a pgp-agent running. Say:

   qpass () { gpg -d ~/passwords.asc | grep $1; }

I.e. Bob encrypted a bunch of critical files and left the company. While I don't want someone that hacks into the server to be able to decrypt them (so the key must be kept in a separate location, like Bob's head) I do want to make sure I can decrypt the files under those special circumstances, but they have to be stored in a way that makes them hard to get.
