v2_6_3 - Show latest stable - Class: OpenSSL::PKey::DH

generate(p1, p2 = v2)

public

Creates a new DH instance from scratch by generating the private and public components alike.

Parameters

size is an integer representing the desired key size. Keys smaller than 1024 bits should be considered insecure.
generator is a small number > 1, typically 2 or 5.

static VALUE
ossl_dh_s_generate(int argc, VALUE *argv, VALUE klass)
{
    DH *dh ;
    int g = 2;
    VALUE size, gen, obj;

    if (rb_scan_args(argc, argv, "11", &size, &gen) == 2) {
        g = NUM2INT(gen);
    }
    dh = dh_generate(NUM2INT(size), g);
    obj = dh_instance(klass, dh);
    if (obj == Qfalse) {
        DH_free(dh);
        ossl_raise(eDHError, NULL);
    }
