Web[Solved]-Generating a SHA256 hash with Crypto++, using a string as input and output?-C++ score:20 Accepted answer This line will give the wrong results: unsigned int nDataLen = sizeof (pbData); It will always give you the size of a pointer. What you want instead is data.size (). Also, you don't need this part: WebDec 9, 2012 · A sha256 hash is 256 bits, or 32 bytes. Thus for the second round you should be hashing a piece of data that's 32 bytes. When hashing a hexadecimal string as the literal input for the second round, your data is 64 bytes. Try a hashing tool that can interpret hexadecimal input.
