GPG as part of your workflow is just as easy (encrypt out with your 
key), but if sending something to someone and don't want to have to 
explain private/public keys and such, I just use OpenSSL, eg:

to encrypt:

openssl bf -in file_to_encrypt -out encrypted_file.bf

to access:

Use OpenSSL to decrypt file with blowfish

openssl bf -d -in file_to_decrypt.bf -out decrypted_file

You'll have to deal with a password prompt, and while you could stash a 
password file and include it for convenience at that point probably 
better to look at using GPG... HIH
