**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.
