Encrypt and decrypt files using openssl

Here's a safe way to pass sensitive files over email...

To encrypt use:

openssl enc -e -bf-cbc -in <FILE.zip> -out <FILE.ENC>

This will ask you for a password that you'll need to decrypt the file.

And to decrypt:

openssl enc -d -bf-cbc -in <FILE.ENC> -out <FILE.zip>
