Why no source code?!!

Share it, please!

I agree, strange to see something without source code here.

I'm also interested in the source code and it's frustrating to not have access, it seems this was written in c++ so cannot be decompiled either. I'd like to see how save files (AC4BF) are being encrypted/decrypted to try delete death flags from wildlands save files rather than the save scumming currently used.

yes, I would like this tool for other games too

For anyone wondering: I contacted the author. He said there's no plan to open source this tool at the moment. However he explained the encryption algorithm as follows:
"The encryption for AC saves is pretty straightforward. It's just a simple XOR in ECB mode:

0. Calculate the MD5 hash of your account ID.
1. Populate encryption key using the MD5 hash (16 bytes): Take first and last bytes, and follow by the rest 14 bytes in reverse order.
2. Get the rotation offset based on the save data size: size % 16, and do a right rotation on the key.
3. XOR the key with the save data."

He also stated that sadly Far Cry 6 uses stronger encryption which hasn't been reverse engineered yet (I asked him about it).
