Generate key and certificate for SSL server and client

[hce]

Hi,

I have a set of RSA string keys (N, E, D, Q, P, DP, DQ and QP). Can I
generate a key, ceritificate and CA certificate based on those RSA
string keys (N, E, D, Q, P, DP, DQ and QP) for SSL server and SSL
client? If so, could you give an example how can I call openssl to do
it?

Thank you.

Kind Regards,

Jupiter

First you need a private key file. There is an example in the
AN1_generate_nconf manual page which you can use as a template to feed into
the asn1parse utility which will output the result in DER format.

Once you have that in DER format you can convert the key to PEM and from then
on generate whatever you want with it.
