I'm using Deja Dup on Oneiric Ocelot.

How can I make it use AES 256 as the algorithm for encryption?

Or for that matter, how can I control which encryption algorithm is used?

Deja Dup uses duplicity which in turn uses GnuPG. GnuPG uses CAST5 by default, but it also supports AES-256. However, I have no idea what parameters Deja Dup passes to duplicity and what parameters duplicity passes to GnuPG. So... how can I control which algorithm is used?

I know this is a bit late but if you put s2k-cipher-algo AES256 in ~/.gnupg/gpg.conf then all your deja-dup backups will be encrypted with AES256. The only downside to this is that if you didn't have this option enabled from the first backup, all your other backups become pointless at that point because you'll need to delete them all and start over. So before you set the option please pick your backups for files that need to be kept.

Thanks, anyway, I started using duplicity directly. Much more control and I know what's going on. –  user12681 May 12 '12 at 12:07

Per Michael Terry, "Deja Dup uses the default in GnuPG, which as of this writing is CAST5. This can't be changed via Deja Dup."
