Certificate Signing Request (CSR) Generation

When applying SSL cert, very common to have generate some public key and private key for signing.

Here to generate a private key first

$openssl genrsa -des3 -out subdomain.domainname.com.key 1024

Then, generate a certificate request file (csr) using the private key you have generated on previous step.

$openssl req -new -key subdomain.domainname.com.key -out subdomain.domainname.com.csr

You will be asked to enter some information. The last two extra option can be left blank.

Then just submit your CSR file to your SSL cert.
