[App] decrypt spm J/K/M

Post by zoelechat »

Binary that decrypts individual encrypted widget files (*.spm).

Code: Select all

usage: decrypt_spm <license_file> <spm_file>
Extract decrypt_spm to SYSROOT/usr/bin, and find ID of widget you want to decrypt files using command:

Code: Select all

wascmd -l
There get "app_package_name" value, e.g.:

Code: Select all

[...]
--------------app_tizen_id                          =9Ur5IzDKqV.TizenYouTube-------------
--------------app_package_name                      =9Ur5IzDKqV-------------
[...]
Then you'll find widget.license file to be used as first arg of decrypt_spm:

Code: Select all

/opt/usr/apps/<app_package_name>/res/widget.license
Encrypted files are to be found in widget folder too, often in a squashfs image with .tmg extension (you can browse with 7zip for example). Anyway if you need to decrypt spm files, it means you know where they are :)
Only one file (.spm passed as 2nd arg) is decrypted at once and written to original folder, make batch by yourself if needed.
