efficient cryptographic hash implementations for bytestrings

 This package provides efficient cryptographic hash implementations for strict
 and lazy bytestrings. For now, CRC32 and Adler32 are supported; they are
 implemented as FFI bindings to efficient code from zlib.
 .
 This package provides a library for the Haskell programming language.
