A quick way to generate self-signed certs through PowerShell

code snippet to generate a 10-year SSL self-signed cert, notice the NotAfter argument.

New-SelfSignedCertificate -DnsName "i7host" -CertStoreLocation "cert:\LocalMachine\My" -KeyAlgorithm RSA -KeyLength 2048 -NotAfter (Get-Date).AddYears(10)
