Can anyone recommend a good in-line file encryption utility. I had a quick
look at bcrypt, but that seems to be intersctive.

I really want to be able to tar|bzip2|encript|ftp from a cron task.

Cheers,
Tony

mcrypt for symmetric, GPG or openSSL for asymmetric.

I would use an asymmetric cipher to avoid having the password in clear
in the cron job.

Eg use RSA, and encrypt the messages with your *public* key. You and
only you will be able to decrypt them with your *private* key.

You can do this with gnupg quite easily. Don't sign the messages
otherwise you'll need to enter your password. You'll need to make
sure you trust your own key ultimately also.

Eg...

$ cat test.txt
This is a test file to be encrypted

$ gpg -e -r FF3B54FA test.txt

$ gpg -d test.txt.gpg
You need a passphrase to unlock the secret key for
user: "Nick Craig-Wood <nick(a)craig-wood.com>"
2048-bit ELG-E key, ID 6A4DDF21, created 2001-09-27 (main key ID FF3B54FA)

gpg: encrypted with 2048-bit ELG-E key, ID 6A4DDF21, created 2001-09-27
"Nick Craig-Wood <nick(a)craig-wood.com>"
This is a test file to be encrypted
