Well here's the problem right here: when you assign a char array to an
std::string using operator=, as you do in "digsignature=buffer;", the
assignment operator treats the char array as a C string, meaning NUL-
terminated; if your signature happened to contain NUL bytes, the
resulting std::string would be truncated. You should use one of the
mechanisms that allows specifying the length of the data instead; for
example, construct digsignature as follows:
std::string digsignature(buffer, size);
