Librsync is a library for calculating and applying network deltas,
|
|
with an interface designed to ease integration into diverse network
|
|
applications. Librsync encapsulates the core algorithms of the rsync
|
|
protocol, which help with efficient calculation of the differences
|
|
between two files. The rsync algorithm is different from most
|
|
differencing algorithms because it does not require the presence of
|
|
the two files to calculate the delta. Instead, it requires a set of
|
|
checksums of each block of one file, which together form a signature
|
|
for that file. Blocks at any point in the other file which have the
|
|
same checksum are likely to be identical, and whatever remains is the
|
|
difference.
