This package provides efficient implementations of routines for applying bitwise XOR masks to binary data.

The currently supported operations (see Data.XOR API documentation for more details) are applying

  • 8-bit wide XOR masks or

  • 32-bit wide XOR masks

to binary data represented by

  • Strict ByteStrings,

  • Lazy ByteStrings,

  • ShortByteStrings (i.e. ByteArray#s), or

  • CStringLen (i.e. Ptrs).

The performance is comparable to portable ISO C99 implementations but this library is implemented as pure Haskell and is thereby compatible with compile targets such as GHCJS.
