adler32: An implementation of Adler-32, supporting rolling checksum operation

[ bsd3, cryptography, hash, library ] [ Propose Tags ]

This package provides an implementation of the Adler-32 checksum algorithm. In supports a rolling checksum mode, i.e. the checksum of a sliding window of the input message can be computed efficiently. It also supports compounding, i.e. the checksum of the concatenation of two messages can be efficiently computed from the checksums of the two parts.

By default, the highly optimized implementation of Adler-32 from zlib will be used. This can be disabled in which case a pure haskell implementation will be used instead. The haskell version is 2 to 3 times slower on my system.
