“Finite Field Arithmetic.” Chapter 14B: Barrett's Modular Reduction. (Part 2 of 2.)

This article is part of a series of hands-on tutorials introducing FFA, or the Finite Field Arithmetic library. FFA differs from the typical “Open Sores” abomination, in that — rather than trusting the author blindly with their lives — prospective users are expected to read and fully understand every single line. In exactly the same […]
