1 year ago Hey,
I think the reason you're getting the error is because your digest does not have the right size. You selected SHA256, but only provided 8 bytes as a digest - you need to use 32 bytes. So if you replace val with vec![0xff;32] or something like that, it should work.

}
The error is ERROR:esys:src/tss2-esys/api/Esys_Sign.c:105:Esys_Sign() Esys Finish ErrorCode (0x000001d5)
