I just learned how to do this using gpg:

$ gpg -c filename

this creates filename.gpg and then you must delete filename.  You may
want to overwrite the file before deleting it to make sure it's gone.
The -c option uses a symmetric cipher.  You could use -e also which, I
think, give you more encrypt option.

To decrypt:

$ gpg -d filename.gpg

This spits the decrypted file to stdout.  You can pipe it to a file as
well. 

I'm still learning, but this is where I am now.  I hope this helps get
you started.
