Hacking [Release] CDecrypt v3.0

[phacox_cll]

I recommend using the most current implementation of CDecrypt made by VitaSmith: HERE



OLD v3.0:

Small application that allows unpack (decrypt) Wii U NUS Content.

Download

This is a fork of a fork made by neobrain of the abandoned CDecrypt originally made by Crediar.

Internally it works almost the same as version 2.0b but it differs in these aspects:

- Remove the Wii U Common Keys from the code. Now need an external file named "keys.txt" where the first line must be the Wii U Common Key and optionally the second line must be the Wii U Common Dev Key.

- Change the command line entry. Now instead of requiring the paths to the files "title.tmd" and "title.tik", requires the path to the NUS Content to decrypt <input path> and the path where you will place the decrypted content <output path>.

- Now lets unpack (decrypt) a specific file, requires the path to the NUS Content to decrypt <input path>, the relative path with the name of the file to decrypt <file to decrypt> and the path where you will place the decrypted file <output filename>.

- Supports paths with non-ASCII characters.

- Supports paths as large as the user's system allows.

Google It... pastebin is your friend.

or you can read the changelog "removed key from sources". so look at the previous sources from previous repositories (or even changelog of 2.1b on github)
but google is often easier and faster for end users.

hey this isn't working for me. i've tried several different ways of decrypting my game but none's working. All it says is this...

Use double quotes for paths with spaces.

i’m confused... double quotes?

Use double quotes for paths with spaces.

if you mean regular quotes like these “ “ i did that. it still just gives me the cdecrypt app details..

Your command is wrong. CDecrypt can't handle "Extract".

1. Copy the folder path to the CDecrypt application
2. Now open up CMD by holding shift (in the game folder) and performing a right click
3. Paste the CDecrypt folder path and append the CDecrypt file name. Then type "title.tmd title.tik" behind it (without ")
4. Press ENTER to start the lengthy) decryption process

Just wait a while till it's finished. Depending on the game size, the can take longer or shorter...Once it's done, you will be back at the CMD prompt.

It should look like this for an example: D:\Backups\Wii U Tools\CDecrypt>CDecrypt.exe title.tmd title.tik

wait but this version tells me not to use that command anymore. I thought that command was for the old version because the post says it was changed

In this version the command input is different from the original CDecrypt.

I have been doing tests to replicate the problem, certainly my version of CDecrypt behaves out of the expected as it should show:

The "C:\Users\JustKeepWalking99\Downloads\Wii" path not exist.

To indicate that the path is being cut in the first space (as in the first image).

Adding the quotes solves the problem (second image).

This is the command I use. And it unpacks the contents like a charm.

 

[gamer20088]

I need help with the app. Can someone tell me the exact command for the decryption app and why not used 2.0 instead?

 

[phacox_cll]

It is the same as using version 2.0 except what is mentioned in the original post (change the command line entry, supports paths with non-ASCII characters, etc.).

Usage:
CDecrypt "C:\Path\to\input" "C:\Path\to\output"

Will this work on the Steam Deck in Desktop mode? Finding Cdecrypt very confusing on the Deck.
