# Fast base64 support [](https://hackage.haskell.org/package/base64-bytestring) [](https://www.stackage.org/package/base64-bytestring) [](http://travis-ci.org/haskell/base64-bytestring)
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](https://github.com/haskell/base64-bytestring).
