Mar 30, 2015 1. Type the following command in an open terminal window on your computer to generate your private key using SSL: $ openssl genrsa -out /path/to/wwwservercom.key 2048. This will invoke OpenSSL, instruct it to generate an RSA private key using the DES3 cipher, and send it as an output to a file in the same directory where you ran the command. Hit Enter to generate your private key. To generate a self-signed SSL certificate using the OpenSSL, complete the following steps: Write down the Common Name (CN) for your SSL Certificate. The CN is the fully qualified name for the system that uses the certificate. Openssl genrsa -out rsakey.pem 1024 openssl req -new -key rsakey.pem -out rsa.csr Finally, you generate the DH cert from the RSA CSR and the DH public key. It is not possible to create a self signed DH cert because (as noted above) DH is not a signing algorithm. It fails because code001.private only contains an RSA key, while pkcs12 expects a certificate to go with it. In addition, as said by Stephane, the -nokeys option will cause openssl to skip the private key. You can generate a certificate with. Openssl req -new -x509 -key code001.private -out code001.pem. To generate private (d,n) key using openssl you can use the following command: openssl genrsa -out private.pem 1024 To generate public (e,n) key from the private key using openssl you can use the following command: openssl rsa -in private.pem -out public.pem -pubout.
