Hi Ingo,
what i want is sign the RIPEMD128 hash and the sign it. I choose RSA
because it is most common and available in cryptopp, and its signature
scheme use SHA1...
Variable string Sign is the end of StringSink, i define it in class Sign
(chek my last post) and i initialize that so:
void SignHash()
{
DigitalSign = "";
}
