CDM-Device-Checker

Easily parse the cdm device info response from: https://tools.axinom.com/decoders/LicenseRequest

SITE STATUS: WORKING BUT LIMITED

GUI Version here: https://github.com/zackmark29/CDM-Device-Checker/releases/tag/v1.0.0-2022-10-03

TIPS:

Add context menu for easy check from challange.txt or client_id_blob

INSTRUCTIONS:

Just double click the add_context_menu.bat to automatically add context menu into your registry
You can also change the context title ("Check Client Id Blob") inside the bat file
Now you can do like the ss below or you can just drag and drop the file in the bat file

From client_id_blob

From challange.txt

CHANGELOGS

[1.0.8] | 2022-04-27

Fixed error when using the context menu with path that has blank/space
Disabled parsing from axinom (temporarily maybe)
Only accept and parse client_id_blob information

[1.0.7] | 2022-01-28

Automatically run "add_context_menu.bat" as admin
Don't write challenge.txt automatically
Print client id blob basic info if --quite mode enabled
Prompt to load challenge from "challenge.txt" if input is empty
Colored is now optional (see config.py)
- NOTE: For windows 7, if you want to print colored text, you can use ansicon.
- INSTRUCTIONS:
  - Extract the zip file
  - Take the folder (x86 if you are using 32bit / x64 if 64bit) and place somewhere and then add the binary to your Environment Variables
  - Simply run for the first time in your cmd: ansicon -i
  - Now it should be injected to your cmd and colored text should show normally.

[1.0.6] | 2022-01-23

Saving file is now optional (add --save arg to save the file)
Added os_version info

[1.0.5] | 2022-01-08

Removed context_menu.reg and replaced with batch file instead to automatically assign the current check.bat full path
Added current full path in check.bat instead of adding manually
Renamed proto to wv_proto to avoid conflict from proto import
colored output for device info and logger
You can edit the output file name format (see in config.py)
And some little changes

SAMPLE OUTPUT:

[1.0.4] | 2021-12-27

1087720375 | Added registry context menu for easy check from challange.txt or client_id_blob
1087669514 | Fixed iterating on NoneType item

[1.0.3] | 2021-12-21

python 3.6-later compatibility
Removed dictionary merge operator "|"
Removed test argument. Just load the test challenge from "challenge.txt" (e.g. py check.py chalenge.txt)

Added base64 validation
Display if revoked or active
Modified output file name with additional info (e.g. ChromeCDM-20122-L3-[ACTIVE].json)
Can now load challenge base64 from txt file or client_id_blob with/without extension .bin
Final output file path will be on the location of input file path
And some minor changes

[1.0.2] | 2021-12-09

Fixed matching client type
Print device info by default. Only use quite option for client_id_blob info
Save challenge base64 to txt file if parsing client_id_blob (so you can verify from https://tools.axinom.com/decoders/LicenseRequest)

[1.0.1] | 2021-12-04

Added protobuf for parsing client_id_blob
Extract challenge directly from client_id_blob file
Fully refactored for getting/matching device info
Added arguments (see --help)
Display the error if found in the response

USAGE

py.check.py "challenge base64 string"
py.check.py "device_client_id_blob"
py.check.py "challenge.txt"
