I'm guessing you are referring to the new format they released with Chitubox 1.9 that encrypts portions of the layer data.

The format is in the CTBEncryptedFile.cs of the UVTools project, and the encryption specifically is handled in the CryptFile mehtod: https://github.com/sn4k3/UVtools/blob/master/UVtools.Core/Fi...
