Use std::ostrstream and the << operator:
#include <strstream>
std::ostrstream oss;
CryptoPP::Integer i("123");
oss << i;
oss << std::ios::hex << i; // use this for hex output
std::string s(oss.str()); // output is now in s

Subject: How can I convert Integer to string
recently I find the crypto++ source code,I want to use ECP.
There is a question for me to resolve:
How to convert integer to string?
I find a message as this:
How to output a Integer as string(Decimal/Hex)? I just can do this:
Integer plaintext;
byte* buffer=new byte[1024];
for (int i=0;i<plaintext.ByteCount();i++)
buffer[plaintext.ByteCount()-1-i]=plaintext.GetByte(i);
buffer[plaintext.ByteCount()]=0;
StringSource(buffer,plaintext.ByteCount(), true,
new HexEncoder(
new FileSink(cout)));
But not fit me,How can I do?
