Confuser is a free open-source software protection tool for .NET applications. It is designed to protect .NET code from reverse engineering by making it difficult for a hacker to understand the code. It does this by obfuscating the code, adding extra layers of complexity and encrypting the code so that it is unrecognizable to the hacker. It also adds code to detect tampering and prevent the code from being modified or redistributed. Confuser also provides features such as anti-tampering, anti-debugging, and anti-decompilation, making it a powerful solution for protecting .NET applications.
