Create SECKEYPublicKey from raw materials

[Andrew Fan]

Hi,

I want to create a RSA public key ( SECKEYPublicKey ) from RSA moduls 
and exponent. I can not find the functions. What can I do? Can you tell 
me the process?

I also want to convert othe mechanism( such as DSA ) raw public 
materials into SECKEYPublicKey. Hope you give me some advices.

Thanks in advance.

Andrew
