Hello, I am using the CryptoPP::Integer class for RSA operations. My program
needs to interact with PHP functions on a server.
My issue comes into play when storing RSA keys, that they appear to remain
in CryptoPP's Integer format, not hex. So after looking around online I
found an implementation for Integer -> std::string
std::string IntegerToString(const Integer refs) {
std::ostrstream oss;
oss << refs;
oss << std::hex << refs; // use this for hex output
std::string s(oss.str());
return s;// output is now in s
}
however, this makes some really interesting decimal output on some of the
numbers, so I added a line to truncate these decimals
std::string xxz568::IntegerToString(const Integer refs) {
std::ostrstream oss;
oss << refs;
oss << std::hex << refs; // use this for hex output
std::string s(oss.str());
s = s.substr(0, s.find_first_of("."));
return s;// output is now in s
}
My only problem now lies with the fact that when I feed a hexidecimal string
to the Integer constructor, and then call the above function on it, all of
the hex values (a-f) are gone, but the numeric values still remain.
How can I fix this?
