Adler-32 Adler-32 is a checksum algorithm which was invented by Mark Adler in 1995,〔(First appearance of Adler-32 (see ChangeLog and adler32.c) )〕 and is a modification of the Fletcher checksum. Compared to a cyclic redundancy check of the same length, it trades reliability for speed (preferring the latter). Adler-32 is more reliable than Fletcher-16, and slightly less reliable than Fletcher-32.〔(Revisiting Fletcher and Adler Checksums )〕 == History ==
The Adler-32 checksum is part of the widely used zlib compression library, as both were developed by Mark Adler. A "rolling checksum" version of Adler-32 is used in the rsync utility.
