WebSHA256 uses a block size of 512 Bit = 64 byte and resulting digest is 256 Bit = 32 byte long. You can also use your own block size and outcome size but for a realistic approach we stick to the original sha256 standard. Now we need to implement the init, update, final and copy functions for our own sha256 implementation. Web22 de mai. de 2012 · I'm looking to create a hash with sha256 using openssl and C++.
