random-bytestring (hackage): This package is deprecated. Please, use genByteString from the random package (version &gt;=1.2) instead.  Efficient generation of random bytestrings. The implementation populates uninitialized memory with uniformily distributed random 64 bit words (and 8 bit words for remaining bytes at the end of the bytestring).  Random words are generated using the PRNG from the mwc-random package or the pcg-random package. It is also possible to use a custom PRNG by providing an instance for the RandomWords type class and using the function generate from the module Data.ByteString.Random.Internal.  The generated byte strings are suitable for statistical applications. They are not suitable for cryptographic applications.
