Version 0.04 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.
Short usage docs are available at http://sourceforge.net/docman/display_doc.php?docid=26727&group_id=129038. For bug reports, please contact the project's administrator.
This is a minor release. Major changes are fixing the build system to support the *BSD platforms, and tweaking the default values less predictable (and thus, for more secure) block interruption.
