Do we have any SHA256 implementation for XMOS?

We have an SHA2 hidden in the sc_crypto project on the XCore Github:

Sounds great!
Do we have any performance estimates for this implementation?

Got it running!
Also got some problems - I do not understand the use of
in
https://github.com/xcore/sc_crypto/blob ... rc/main.xc
I feel I missed something in the middle, The SHA256 hash for test message (including this modification with 0x80) is correct, while I am trying to test with other test vectors I am getting result far beyond expected hash.
Any comments quite appreciated!

I'll forward this onto the person who created it here at XMOS, they're the most likely to solve your problem.
