Fast base64 support Hackage version Stackage version Build Status

This package provides a Haskell library for working with base64-encoded data quickly and efficiently, using the ByteString type.

Performance

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 GitHub issue tracker.

Master Git repository:

  • git clone git://github.com/haskell/base64-bytestring.git

Authors

This library is written by Bryan O’Sullivan. It is maintained by Herbert Valerio Riedel and Mikhail Glushenkov.
