I wanted to create a similar ProtectionID but for .NET. ProtectionID has some .NET detection but I saw there aren't some obfuscators.
Features:
Easy to use: Just drag and drop the assembly and see the results.
Good detection: although there are some obfuscators that are difficult to detect because they don't leave a good signature, this application can "guess" the obfuscator.
Nice information: Gives you some .NET information (like language, entrypoint, ...) and also gives how many days are left if it's a trial version.
I hope this can be useful for anyone.
To-do list:
Improve detection of the obfuscator version
Tips to deobfuscate/unpack it (like ExeinfoPE).
Detect native protection (for example DotNet Reactor).
