I usually use container or sometimes tools like ccrypt to do (simple) file encryption from the command line in Linux but it has come to my attention that there is an easier way to do file encryption with OpenSSL. From the command line on *nix machines that have OpenSSL you can try the following.

To encrypt the file my1test.txt and ouput to the file my1test.aes.

openssl aes-256-cbc -a -e -salt -in my1test.txt -out my1test.aes

To decrypt the file my1test.aes and ouput to the file my1test-decrypt.txt.

openssl aes-256-cbc -a -d -salt -in my1test.aes -out my1test-decrypt.txt

This just makes file encryption easier because you can use any machine with openssl to encrypt or decrypt the same file. BSD, Linux, Solaris, Irix, etc. No more installing extra programs to do this if you really don’t want to.
