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.
