librsync, the network delta compression library

librsync does network delta compression of arbitrary binary files. It implements the same algorithm as rsync, but not the same network protocol.

librsync provides three main operations:

  • generate a signature S from a file A
  • generate a delta D from S and a new file A1
  • apply D to A to reconstruct A1

The librsync source package also provides the rdiff command-line interface.
