Fast base16 support

This package provides a Haskell library for working with base16-encoded data quickly and efficiently, using the ByteString type.


This library is written in pure Haskell, and it's fast:

  • 250 MB/sec encoding

  • 200 MB/sec strict decoding (per RFC 4648)

  • 100 MB/sec lenient decoding

Get involved!

Please report bugs via the bitbucket issue tracker.

Master github repository:

  • git clone git://

There's also a Mercurial mirror:

  • hg clone

(You can create and contribute changes using either git or Mercurial.)
