2021-07-12	lib/crypto-algorithms: Move crypto-algorithms code from extmod to lib.	Damien George
	It's third-party code, and not necessarily tied to extmod. Signed-off-by: Damien George <damien@micropython.org>
2021-06-24	all: Fix signed shifts and NULL access errors from -fsanitize=undefined.	Jeff Epler

However, for the purposes of undefined behavior analysis the conditional is needed. Signed-off-by: Jeff Epler <jepler@gmail.com>
2019-08-22	extmod/crypto-algorithms: Add source to header and populate copyright.	Damien George
	As per the README.md of the upstream source at https://github.com/B-Con/crypto-algorithms, this source code was released into the public domain, so make that explicit in the copyright line in the header.
2017-04-27	extmod/crypto-algorithms/sha256: Remove non-standard memory.h header.	Paul Sokolovsky

2015-12-20	extmod/moduhashlib: Add namespace prefix for crypto-algorithms/sha256.h.	Paul Sokolovsky
	Everyone loves to names similar things the same, then there're conflicts between different libraries. The namespace prefix used is "CRYAL_", which is weird, and that's good, as that minimizes chance of another conflict.
2015-03-19	extmod/crypto: Add static keyword where it should be.	Damien George

2014-11-22	moduhashlib: Add sha256 implementation from "crypto-algorithms" project.	Paul Sokolovsky
