Huawei backup decryptor
This script is introduced by the blog post at https://blog.digital-forensics.it/2019/07/huawei-backup-decryptor.html.
The kobackupdec
is a Python3 script aimed to decrypt Huawei HiSuite or KoBackup (the Android app) backups. When decrypting and uncompressing the archives, it will re-organize the output folders structure trying to mimic the typical Android one. The script will work both on Windows and Linux hosts, provided the PyCryptoDome dependency. Starting from 20100107 the script was rewritten to handle v9 and v10 kobackup backups structures.
The script assumes that backups are encrypted with a user-provided password. Actually it does not support the HiSuite self generated password, when the user does not provide its own.
usage: kobackupdec.py [-h] [-v] password backup_path dest_path
Huawei KoBackup decryptor version 20200611
positional arguments:
password user password for the backup
backup_path backup folder
dest_path decrypted backup folder
optional arguments:
-h, --help show this help message and exit
-e, --expandtar expand tar files
-w, --writable do not set RO pemission on decrypted data
-v, --verbose verbose level, -v to -vvv
password
, is the user provided password.backup_path
, is the folder containing the Huawei backup, relative or absolute paths can be used.dest_path
, is the folder to be created in the specified path, absolute or relative. It will complain if the provided folder already exists.[-v]
(from-v
to-vvv
) verbosity level, written on stderr. It's suggested to use -vvv with a redirect to get a log of the process.

The output folder structure will be similar to the following one: data/data applications will be exploded in their proper paths, and the APKs will be restored too (not icons, actually). Note that the db folder will contain the special databases as created by the Huawei backups.
