[Interest] hmac sha256

[Jérôme Godbout]

Hi,
I'm trying to find the C++ equivalent of this python:
*import hashlib*
*import hmac*
*hmac.new(bytearray(m_api_secret, 'utf-8'), bytearray(payload, 'utf-8'),
hashlib.sha256).hexdigest()*

Or my Javascript equivalent (both give the same results):
crypto.createHmac("sha256", m_api_secret).update(payload).digest("hex");

I have try the following:

   - QMessageAuthenticationCode::hash(payload,
   QByteArray::fromHex(m_api_secret), QCryptographicHash::Sha256).toHex();
   - QMessageAuthenticationCode::hash(payload,
   QByteArray::fromHex(m_api_secret), QCryptographicHash::Sha3_256).toHex();
   - QMessageAuthenticationCode::hash(payload, m_api_secret,
   QCryptographicHash::Sha256).toHex();
   - QMessageAuthenticationCode::hash(payload, m_api_secret,
   QCryptographicHash::Sha3_256).toHex();
   - QMessageAuthenticationCode::hash(QByteArray::fromHex(payload),
   QByteArray::fromHex(m_api_secret), QCryptographicHash::Sha256).toHex();
   - QMessageAuthenticationCode::hash(QByteArray::fromHex(payload),
   QByteArray::fromHex(m_api_secret), QCryptographicHash::Sha3_256).toHex();

But I never get the same results as the Python or Javascript one. Maybe I'm
using the wrong class here. Anybody have a good pointer on how to do this?
Any good hmac sha256 class to perform this?
