Creating an RSA public key from a modulus and exponent

ruby-talk
1

I know how to create a new keypair using:

OpenSSL::PKey::RSA.new(1024)

But, I'm looking for how to create a public key when I have the modulus
and exponent value of that key. Any help would be appreciated.

Thanks,

rodney

OK, after many hours of playing I've answered my own question and posted
it on my blog. Here you go:

How did you get them into that format though? I have been trying the
smae thing for the better part of a week and can't get them into the
correct format.
