This is impossible as a non-breaking change, because the template parameter comes from CryptoPP.

There does not seem to be a clean way to implement Sha256 using the security::transform framework. The former is inherently incremental, whereas a transform chain expects all its input to be available in one go and when the input is exhausted the digest gets finalized.

Any ideas?
