libdecaf:sha3_256 with data larger than 20 KB is not working #7

Closed sunboshan closed 2 years ago

sunboshan commented 5 years ago

Calculate hash for data larger than 20KB is not working. However if use init, update, final it will work.

Maybe a bug?

libdecaf version is 1.0.0

This should be fixed as part of libdecaf version 2.0.0.
