Every night I'm running a cron backup script, that gathers the files that I think is essential for the system and stores then in Info-ZIP archives. What I really would like is to encrypt these archives, but is it possible to do this without user input ?

Thanks in advance /flywheel

In short yes it is.

The real question is why are you encrypting them, and where are you storing them once encrypted. You can use a couple of methods to encrypt the data, but you will need to have a key, or password stored in the script or on the box doing the encrypting. GPG is a simple method of doing this, there are much more complicated version of this procedure as well.

To encrypt the file you would use something like:

gpg –yes –passphrase [MY PASS PHRASE] -c [FILENAME]

not the -c tells is to use symmetric encryption

and to decrypt the file:

gpg –yes –passphrase [MY PASS PHRASE] [FILENAME]

Jeez - I spent 20 minutes with the gpg documentation and never saw that - I wonder what else I have missed over the years.

Cool - many thanks
