Re: how to get the e and d in rsa of crypto++ library?

[Haytham Mohammed]

Hi

 

I think that it is a problem of printing the output.

 

try to put your output in an Integer object.

Integer d = privkey.GetDecryptionExponent();

Integer q = privkey.GetPrime2() ;

Integer e = privkey.GetExponent();

 

and use the Integer Object functions like ByteCount() and GetByte()

 

I think that GetExponent and GetDecryptionExponent() functions always return 1 to you because the second byte value in the (Integer Object returned) equals 0.

I use crypto++ v4.2 !
My code is below:

void GenerateRSAKey(unsigned int keyLength, const char *privFilename, const
char *pubFilename, const char *seed)
{
RandomPool randPool;
randPool.Put((byte *)seed, strlen(seed));


RSAES_OAEP_SHA_Decryptor priv(randPool, keyLength);
InvertibleRSAFunction privkey(randPool, keyLength);

cout << "d= " << privkey.GetDecryptionExponent()<< endl;
cout << endl;
cout << "p= " < cout << endl;
cout << "q= " << privkey.GetPrime2() < cout << endl;
cout << "e= "<< privkey.GetExponent() << endl;
}
Thank in advanced!
