Encrypted backups (without the backups).
encbup is a companion to bup, the backup program. encbup adds encryption to bup, while still allowing per-file deduplication.
encbup can be thought of as an encrypted version of tar. It accepts a list of files and produces an encrypted blob.
To encrypt:
encbup.py --encrypt - /my/data/dir/ /some/file
To decrypt:
encbup.py --decrypt - /my/outdir/
