How to Create a Self-Signed Certificate in Windows Server
INTRODUCTION
In cryptography and computer security, self-signed certificates are public key certificates that are not issued by a certificate authority. These self-signed certificates are easy to make and do not cost money. However, they do not provide any trust value. On modern Windows versions (Windows Server 2022/2019/2016/2012R2) you can create a self-signed certificate using the built-in PowerShell cmdlet [New-SelfSignedCertificate](https://learn.microsoft.com/en-us/powershell/module/pki/new-selfsignedcertificate?view=windowsserver2022-ps)
