Create Self Issued Wildcard Certificates with MakeCert

When creating test labs etc its often necessary to use and create SSL certs. Making your own self issued one is easy with Microsoft’s tool Makecert.

Download the tool. Run an elevated command prompt and run the following command.

makecert -r -pe -n "CN=*.yourdomain.com" -b 01/01/2010 -e 01/01/2100 -eku 1.3.6.1.5.5.7.3.1,1.3.6.1.5.5.7.3.2,1.3.6.1.5.5.7.3.3,1.3.6.1.5.5.7.3.4 -ss my -sr localMachine -sky exchange -sp "Microsoft RSA SChannel Cryptographic Provider" -sy 12 -len 2048

This will now produce the cert and put in your personal certificate folder in the local machine. Export this to a PFX with the private key and you can now import it to as many servers as you want..
