adler32: An implementation of Adler-32, supporting rolling checksum operation
This is a package candidate release! Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.
This package provides an implementation of the Adler-32 checksum algorithm. It 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. On my system, the haskell version
is 2 to 3 times slower.
