The standard encryption technology for linux is LUKS. It works on the
block device level, not the file level. [I may be using the terminology
inaccurately.] You'll find the best compatibility, stability, and
documentation with LUKS, but you don't use it to create encrypted
copies of files - rather, you create a LUKS encrypted device, and
copy / move your files there. The LUKS tools (cryptsetup) are only
necessary for the creation and management of the encrypted volume; once
it's set up, you use the ondinary filesystem tools (cp, mv, ls, etc.)
to access files and move them to and from encrypted storage.

I believe that the most commonly used software for file level
encryption is EncFS. I haven't really used it much, and can't speak to
its long term stablity.
