math - C++ how to make simple sha256 generator with boost? -

-

i need simple string sha256 generator class. not want build big libraries openssl or cripto++ - want turn strings sha256. how create such class or it?

like others have said, under impression hashing under sha256 not trivial enough implement subset of bigger coding project. if take @ wikipedia page sha-2, notice pretty intense math. if actual encryption abstract (the math theory itself), can found here. if you're programmers emphasis not in security, want use else's tested , tried implementation. can find few here. let me know if helped. sorry couldn't answer question straight code or of nature.
