Topic: i read a openssl code ?

it works like this :
use this public key:

-----BEGIN RSA PUBLIC KEY-----
MIGJAoGBANA0SPVdEgBMCBo4WMeKl6lEM8swJsu+8Rq0usMkdcq8GxsD445x+EtF
+Dmalx6rSR5M7mNARLdsALd2pr3HVLuSSe4bCC26u1PBsOVeszhEzdr7NWiGy3bI
fW6ddTCt0VMC75PrsVmCB2oavp8GKI09Y0TsegxiM6MN6bj33eJtAgMBAAE=
-----END RSA PUBLIC KEY-----

to create a CERTIFICATE like this :

-----BEGIN CERTIFICATE-----
MIICNjCCAR6gAwIBAgIBADANBgkqhkiG9w0BAQUFADAAMB4XDTE0MDQyOTA5NDUx
NloXDTI0MDQyNjA5NDUxNlowADCBnzANBgkqhkiG9w0BAQEFAAOBjQAwgYkCgYEA

Re: i read a openssl code ?

Hi zhbn,

For an example of using CyaSSL key and certificate generation, you can reference the rsa_test() function in <cyassl_root>/ctaocrypt/test/test.c, specifically the code inside of the CYASSL_KEY_GEN and CYASSL_CERT_GEN #ifdef blocks.

CyaSSL will need to be compiled with --enable-certgen to enable certificate generation and --enable-keygen if you want to do RSA key generation.

Best Regards,
Chris
