void ElGamalKeyPairGenerator::operator() (  ElGamalPublicKey *&  pubKey, ElGamalPrivateKey *&  privKey, BIGNUM *  p = 0, BIGNUM *  g = 0 )

Parameters: pubKey  Public key, filled by routine privKey  Private key, filled by routine p  Prime modulus of the form 2q+1 for a prime q. If 0 a new prime is selected and placed in p. g  Generator of the multiplicative subgroup of Z_p. If 0 a new generator is selected and placed in g. Exceptions: BignumNullException  Some memory allocation failed. BignumGeneratePrimeException  There was an error generating a new prime modulus. BignumSubException  There was an error during subtraction. BignumContextException  Memory allocation failed for a BN_CTX. BignumRshiftException  There was an error while bit-shifting a BIGNUM. BignumRandRangeException  There was an error generating the random exponent. BignumModMulException  There was an error during modular multiplication. BignumModExpException  There was an error during modular exponentiation. Definition at line 27 of file ElGamalKeyPairGenerator.cc.
