building on macOS #1

not really an issue, but I wanted to share how to build your Borderland tools on macOS:

install protobuf-c:
```
brew install protobuf-c
```

modify the Makefile:

# Link flags. 
LDFLAGS = -lprotobuf-c -L/usr/local/lib -L/usr/lib -L/opt/homebrew/opt/protobuf-c/lib
CFLAGS = -I. -O0 -I/opt/homebrew/opt/protobuf-c/include

build with make

thanks for sharing your tools 👍 once I fully understand the save structure and your code, I'll try to add the PS4 save decryption to my ps4 homebrew save manager Apollo

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: https://github.com/bucanero/ps3-save-decrypters/tree/master/ps4-borderlands3-decrypter

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.
