Version 0.16 of rsyncrypto has been released today. rsyncrypto is a rsync friendly file encryption, where localized modifications in the plaintext file result in localized modifications in the cyphertext file, to preserve rsync's efficiency over the wire.
In many respects, this is the most important rsyncrypto release to date. New to this version is support for encrypting the names of the encrypted files. Please check out the "-n" option in the man page.
