[German]Nartac Software has already released version 4.0 of its small tool IIS Crypto on February 13, 2025. Support for Windows Server 2025 has been added, as well as support for the TLS_CHACHA20_POLY1305_SHA256 Cipher Suite.
IIS Crypto is a free tool that allows administrators to enable or disable protocols, ciphers, hashes and key exchange algorithms on Windows Server versions 2012 to 2025.
It also allows administrators to rearrange the SSL/TLS cipher suites offered by IIS, change advanced settings, implement best practices with a single click, create custom templates and test their website.
IIS Crypto requires at least Windows Server 2012 and the .Net 4.6.2 framework or higher. Both GUI and command line versions are available. Below is the change log from the download area.
