#Decrypt0r

Choose what you want to do
 1) Decrypt Root Filesystem
 2) Decrypt Ramdisk
 3) Decrypt IMG3 File
 4) Decrypt DFU File
 5) Decrypt Kernelcache
 6) Patch iBEC/iBSS
 7) Save SHSHs blobs
Command :

###Rootfs decrypting

To decrypt rootfs or other components like IMG3 files you have to grab keys from iPhonewiki.

First download the IPSW you choose to decrypt, you can download it directly with my tool or from ipsw.me.
The program will ask you to add the keys grabed from iphonewiki (only one for the rootfs).

Specify the name of the file containing rootfs (ex 058-24465-023.dmg).
In the IPSW file, there is three dmg files, rootfs is the biggest.

Then the program is going to work automaticaly.

If you want to modify rootfs (ex Setup.app) you can use TransMac for Windows. But it won't work to bypass iCloud

Encryption of rootfs and creating a Custom fimware

You can create a Custom fimware but it's crap. Be patient.
Downgrades are already impossible without SHSHs blobs, on devices that do not have low level exploits (RIP Limera1n).
Is this feature useless ?
Yes, but it can still be used.

###IMG3

To decrypt IMG3 files like kernelcache or iBoot, you have to grab the keys from theiphonewiki
The first one to add is the largest, and the second one is the iv key (the smallest).
Then follow instructions.

###How to build it?

To build Decrypt0r just cd to the decryptr0r directory and run make + your_os

If you need to build XPwn for Linux, just run build.sh. OS X users you have to build XPwn yourself, I'll made a bin directory with all the binaries ASAP

###Compatibility

Decrypt0r is compatible with Linux & OS X, Windows users, check Decrypt0r for Windows

###Binaries For people who doesn't want to run my script or are running OS X you have the possibility to download this file which contains OS X, Linux64 & Raspberry Pi binaries
Download here If you want to download an IPSW file from the tool you should install wget
