Yep, I'm working on a software implementation of ECDSA. Currently have the OpenSSL implementation for the nistp256 curve isolated, debugging a test program that verifies a signature on data that was randomly generated, then will need to clean up unnecessary code and fit it into U-Boot.

CC'd my @linux.microsoft.com email, I prefer to use that one from now on.

All the best,
Tim

I don't have any updates from Tim that you don't. I assume he's still silently hacking at it.
