Expand description

Gets the parameters of the ec curve defined by y^2 = x^3 + ax + b (for GFp) or y^2 + xy = x^3 + a*x^2 + b (for GF2m) \param group EC_GROUP object \param p BIGNUM with the prime number (GFp) or the polynomial defining the underlying field (GF2m) \param a BIGNUM for parameter a of the equation \param b BIGNUM for parameter b of the equation \param ctx BN_CTX object (optional) \return 1 on success and 0 if an error occurred
