building on macOS about csave HOT 2 OPEN

Yeah, it works on just about all UNIX flavors (albeit, compiling protobuf-c can be somewhat difficult on some systems). Seems like a lot of people use this program to work with console saves -- I haven't tested it myself (I don't have much interest in it), but I've read that it works fine. Now, as for the save decryption for BL3 saves, that's some BL3-specific thing, it doesn't exist anywhere else (that I could find).

I should really re-write this thing, it was a quick-n-dirty program I wrote to maintain a catalog of all of my BL3 saves (of which I have probably two hundred or so)!

Anyways, good luck!

I was testing with my ps4 saves and the encryption/decryption works fine. I didn't test the other tools, but I think they'd work fine with the ps4 saves too.

Just for reference, here's my simplified code that only decrypt/encrypt the custom protection on PS4 saves:

The encryption is based on a simple XOR process, but as you mentioned this looks like a game-specific custom thing and not a standard encryption algorithm like AES, DES, etc.
