Continuing on with the SHA-256 calculator, we write more routines for copying blocks of memory in different ways, and the remaining low-level functions required by the algorithm. Next time we’ll be moving up a step or two to higher-level parts of the program.

The hat is a Lewis Round Barn hat from the Old Tyme Association. If you’ve been to the Adams County Fair outside Mendon, you know what that’s about. It’s not really my style of hat, but it’s local, so I thought I’d show it off.

Also, I’ve created a Patreon page for my programming videos. There’s no obligation, as all the videos and code will remain free for everyone. But if you’d like to support the project, check it out there with my thanks!
