/**
 * \brief            The PKCS#12 derivation function uses a password and a salt

 *
 *                   Depending on the given id, this function can produce an

 *                   integrity key.
 *
 * \param data       buffer to store the derived data in
 * \param datalen    length to fill
 * \param pwd        password to use (may be NULL if no password is used)
 * \param pwdlen     length of the password (may be 0)
 * \param salt       salt buffer to use
