Paula's Cadenza is software that allows you to log in multiple "bots" concurrently in to Habbo Hotel (the flash version of the Hotel)
This was more-or-less a weekend "hackathon" project. I figured all of this out by using AS3 Sorcerer to decompile the Habbo.swf flash file.
The DHM key exchange cryptography is a C# port of the hurlant AS3 crypto library, specifically the BigInteger library.
This is unfinished as Habbo Hotel is changing everything as they move away from Flash; There was no reason to continue working on it. But, some of you may like to take a look so I am going to keep it here.
The UI is WinForms/.NET Framework 4.8, all the other libraries are .NET Standard 2.0. Built with Visual Studio 2019 Enterprise.
