gpg --symmetric and gpg --decrypt should do what you want.

Simple, use openssl.

openssl enc -aes-256-cbc -salt -in plain.txt -out myultrasecretfile.enc

If you want to compress before, that is your choice.

I would use GPG.

Or, you can use any zip library that supports AES...

Did you try vi -x filename ? It is not exactly full-featured encryption, but it might do what you want.

i like aespipe as you can use it completely non-interactively from command line or scripts, and it will work with any stream of data.
