base16-bytestring: RFC 4648-compliant Base16 encodings for ByteStrings

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). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.

[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 the base16 package which provides superior encoding and decoding performance as well as support for lazy, short, and strict variants of Text and ByteString values. Additionally, see the base-encoding package which provides an uniform API providing conversion paths between more binary and textual types.
