Cat-x.dll - Security class

[Zorno]

Little helper dll for people in need of encrypted strings like for networking etc.
Or for people that want do hook their product to a specific machine (HWUUID).

This dll gives access to those functions:

- sha256 hash of a string (example: string x = cat-x.Sha256("examplestring"); )
- sha512 hash of a string (example: string x = cat-x.Sha512("examplestring"); )
- Md5 hash of a string (example: string x = cat-x.Md5("examplestring"); )
- Rijandel encrypting and decrypting a string by passphrase (example: string x = cat-x.Encrypt("examplestring","examplepassword"); / string x = cat-x.Decrypt("encryptedstring","examplepassword"); )
- getting a hardware uuid based on encrypted string from hardware ids (example: string x = cat-x.GetHardwareUUID(); )
- getting a real random number between 2 numbers based on unixtime as seed (example: string x = cat-x.GetRealRandom(1,100); )

Example for network packages:

string networkkey = "undefinedexamplerandomnetworkkeyforsecuringyournetworkstream";
string packet = "data123456789"
packet = cat-x.Encrypt(packet,networkkey);
byte[] data = Encoding.ASCII.GetBytes(packet);

... send data now. Received bytes can get decrypted the same way. Encoding to string, decrypting by networkkey then use ...

There is also a GetVersion function that shows current version of the dll but this is more for later when i added stuff to this dll

Hope it helps someone. If you need the source you can either decompile (its .NET 5 ... so no thing to decompile) or check my signature (the unity version of it is source and most of the functions are included also ).
