Converts the Whatsapp crypt7 and crypt5 databases to the old crypt database!
Reads the file /sdcard/Whatsapp/Databases/msgstore.db.crypt7 or ...5 and converts it to a file /sdcard/Whatsapp/Databases/msgstore.db.crypt.
Please be patient. After starting Its running in the background and may take some minutes!
You will need root permissions for crypt7 files.
Why? Other apps like SMS Backup+ will work again!
Whatsapp creates the crypt5 backup file every night at 4am.
Whatsapp Crypt-DB Converter will run at 5am and convert the database created at 4am.
Read/modify content of SD card: should be clear.
Find accounts: crypt5 database uses your Google Account Mail address in its key - we need to read it.
Run at startup, prevent phone from sleeping: needed for the 5am convertion
Why root? The key for decrypting crypt7 databases must be retrieved from /data/data/com.whatsapp - this needs root access.
Added support for crypt7. You need root access for crypt7 databases.
