Why doesn't TLS_CHACHA20_POLY1305_SHA256 show up in Windows Server 2022?
When IIS Crypto is first run it loads all of the settings from the registry including a list of default cipher suites supported by the operating system.
Every version of Windows has a different list of supported cipher suites.
Windows Server 2022 and above supports TLS_CHACHA20_POLY1305_SHA256, however, it is not in list of default cipher suites. This is why it is not displayed in IIS Crypto.
All of the templates enable TLS_CHACHA20_POLY1305_SHA256 and move it to the top of the list.
If you do not use a template, it can be added manually by clicking on the Cipher Suites tab and then on the Plus button. The name is TLS_CHACHA20_POLY1305_SHA256
