# picobase64

Very fast and lightweight header encoder/decoder base64 and strlen.

**The fastest library for encoding and decoding base64!**

**THIS IS NOT A JOKE**

# Benchmarks

Additional information on benchmarks, tests and charts see below.

### Tests

*Less time (in microseconds) faster.*

The two fastest encoder implementations I found were Jouni Malinen's at

http://web.mit.edu/freebsd/head/contrib/wpa/src/utils/base64.c

and the Apache at

https://opensource.apple.com/source/QuickTimeStreamingServer/QuickTimeStreamingServer-452/CommonUtilitiesLib/base64.c.
