ADLER32 Overview

ADLER32 is a checksum algorithm that is s a 32-bit extension and improvement of the Fletcher algorithm, used in the ITU-T X.224 / ISO 8073 standard. It can be used to calculate a 32-bit checksum for an arbitrary length byte string.

The ADLER32 algorithm is much faster than the CRC32 algorithm yet still provides an extremely low probability of undetected errors.

The algorithm is not cryptographically strong, and should not be used for authentication or digital signatures. Since the algorithm is designed for use as a checksum algorithm, it is not suitable for use as a general hash algorithm.

The ADLER32 algorithm is specified in RFC1950.
