Allows you to create longer lasting self signed certificates for testing
new-selfsignedcertificate in powershell is pretty good but doesnt allow more than 12 months expiration.
selfssl7 allows up to 50 years and 2048 bit size. Its default behavior is to create and install the certificate – be careful.
