IIS Crypto is a free tool that gives administrators the ability to enable or disable protocols, ciphers, hashes and key exchange algorithms on Windows Server 2008, 2012 and 2016. It also lets you reorder SSL/TLS cipher suites offered by IIS, implement best practices with a single click, create custom templates and test your website.
IIS Crypto updates the registry using the same settings from this article by Microsoft. It also updates the cipher suite order in the same way that the Group Policy Editor (gpedit.msc) does. Additionally IIS Crypto lets your create custom templates that can be saved for use on multiple servers. The command line version contains the same built-in templates as the GUI version and can also be used with your own custom templates. IIS Crypto has been tested on Windows Server 2008, 2008 R2 and 2012, 2012 R2 and 2016.
IIS Crypto requires administrator privileges. If you are running under a non-administrator account, the GUI version will prompt for elevated permissions. The command line version must be run from a command line that already has elevated permissions.
