Version 0.14 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.
New to this version - rsyncrypto now runs on Windows!
This version has been totally revamped to use "libargtable" instead of "getopt_long". As part of the Windows port, there was lots of code movement. It also now sports an automatic regression testing tool.
