Hi Michael,
gpg can also be used for "conventionally" encrypting/decrypting a file based
on a password/passphrase, e.g.:
$ gpg -c foo.txt
Enter passphrase:
Repeat passphrase:
$ ls foo*
foo.txt foo.txt.gpg
[...]
$ gpg foo.txt.gpg
gpg: CAST5 encrypted data
Enter passphrase:
gpg: encrypted with 1 passphrase
gpg: WARNING: message was not integrity protected
$
Probably the easiest way to encrypt/decrypt files via a command line.
Cheers,
Rony
