Store X509 Certificate in database

Question

In order to access to the web service I need a certificate.

I generated my certs:

openssl genrsa 1024 > private.key
openssl req -new -x509 -nodes -sha         


        

Answer 1

So this is actually easy, although I found no simple description of it. I've left the cert strings in my gist (sample cert, no secure data)
