Re: [Perl-openssl-users] new_key_from_parameters question

[Ian R. <iro...@re...>]

Stefan,

The new_key_from_parameters method expects the parameters to be
Crypt::OpenSSL::Bignum objects.  Judging from the Math::Pari man page,
you should be able to convert a Math::Pari bigint object $n to a
C::O::Bignum object by:

my $cob_n = Crypt::OpenSSL::Bignum->new_from_decimal($n->pari2pv());

You'll have to do this for each of the values; alternatively, you can do
it just for n and e, and let C::O::RSA compute the rest for you.  This
latter approach will take a bit longer (in the millisecond range), but
if it's an infrequent operation, might be Good Enough For You.
