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).

[maintain] [Publish]

This package provides support for encoding and decoding binary data according to base16 (see also RFC 4648) for strict (see Data.ByteString.Base16) and lazy ByteStrings (see Data.ByteString.Base16.Lazy).

See also the base-encoding package which provides an uniform API providing conversion paths between more binary and textual types.
