What are db.crypt12 files in the Whatsapp Databases folder?

WhatsApp Messenger, the widely used Android messaging application, generates an encrypted database known as a CRYPT12 file. The messages sent and received through the app are securely stored in a 256-bit AES-encrypted database.

To create backups of user messages, WhatsApp utilizes an encrypted database file with a .DB extension, specifically a .crypt12 file. WhatsApp has consistently employed various encryption techniques to safeguard user messages. If you use WhatsApp, you may encounter encrypted message backups in the form of .CRYPT7, .CRYPT8, .CRYPT10, or .crypt12 files.

To access the message history within a CRYPT12 database, it is essential to identify the WhatsApp key file containing the encryption key for the CRYPT12 file. The key file is located at /data/data/com.whatsapp/files/key.

The data for the CRYPT12 database is stored on the SD card of Android devices running WhatsApp Messenger, and you can find the CRYPT12 file (or any other encrypted database file) at /sdcard/WhatsApp/Databases.

File names in the Databases directory may include YYYY-MM-DD dates, indicating when the backup files were generated. WhatsApp routinely generates new backup files, and the dates in the filenames indicate their creation time. Old backup files can be deleted to free up space on the SD card without affecting WhatsApp communications. However, it is advisable to always keep at least one or two CRYPT12 files if you need to restore your WhatsApp conversation history.

It’s important to note that Crypt12 files are exclusively generated in the Android version of WhatsApp Messenger and are not produced in the iOS version. WhatsApp on iOS or the desktop version does not create CRYPT12 files.

WhatsApp Messenger utilizes a database file named DB.CRYPT12 to store user information, constituting an encrypted conversation history database. The addition of the .CRYPT12 file extension to the .DB file enhances the security of the Android user’s message database. WhatsApp updates its encryption algorithm with each new release, with file extensions such as .CRYPT6, .CRYPT7, or .CRYPT8 indicating the encryption technique employed.

Can you delete db.crypt12 files from your device?

Certainly, you can effortlessly remove db.crypt12 files from your device’s WhatsApp Databases Folder without causing any disruption to the functioning of either WhatsApp or your device.

As these files solely serve as backup files for WhatsApp conversations, they will be regenerated the next time WhatsApp initiates a chat backup. For instance, if you’ve configured the backup frequency to ‘Daily,’ WhatsApp will generate a new db.crypt12 file every day at a specified time. Consequently, deleting the prior db.crypt12 file should not adversely impact your device or your WhatsApp conversations in general.

It’s worth noting, however, that if you decide to delete all db.crypt12 files and subsequently uninstall WhatsApp, you won’t be able to back up your conversations upon reinstalling WhatsApp. Deleting these backup files means losing your chat backup, as WhatsApp won’t create another one (due to the uninstallation). Therefore, it’s essential to consider this consequence before deleting these files.
