Abstract
This chapter explains how to implement BLAKE on software platforms, from simplistic and portable C implementations to assembly for 8-bit AVR microcontrollers. We focus on the implementation of the compression function, as opposed to the operation mode, the latter being straightforward to implement and not performancecritical. Optimized C and assembly implementations of BLAKE for various platforms are included in the SUPERCOP software, available for download from the eBACS project [28]. Complete reference C implementations of BLAKE-256 and BLAKE-512 are given in Appendix B.
