Generate self signed no pass open ssl certificates

Generate self signed no pass open ssl certificates.md

Here is a simplified version that removes the passphrase, ups the security to suppress warnings and includes a suggestion in comments to pass in -subj to remove the full question list:

   $ openssl genrsa -des3 -out server.key 2048
   $ openssl rsa -in server.key -out server.key
   $ openssl req -sha256 -new -key server.key -out server.csr -subj '/CN=localhost'
   $ openssl x509 -req -sha256 -days 365 -in server.csr -signkey server.key -out server.crt

Replace 'localhost' with whatever domain you require. You will need to run the first two commands one by one as openssl will prompt for a passphrase.

To combine the two into a .pem file:

    $ cat server.crt server.key > cert.pem
