Hidden Treasure: WhatsApp Database and What It Stores





Whenever you use WhatsApp, it saves all your chats, media, and group info in a special file called a database file.

This file is saved on your phone, usually in this folder:


Internal Storage > WhatsApp > Databases > msgstore.db.crypt12

But this file is encrypted. That means you can’t open it directly. It is locked with a secret key file.

 The Key File – Where Is It?

To open (decrypt) this database file, you need the key. It is stored deep inside the phone here:

/data/data/com.whatsapp/files/key

But you can’t access this folder normally. You need root access to reach this location. Without root or a proper extraction tool, you can’t get the key.

Some ways to get it (for your own phone only):

  • Root the device

  • Use ADB with root

  • Use tools like Magisk, MT Manager, or forensic software

 How to Decrypt the Database

After you get both files:

  • msgstore.db.crypt12

  • key

Now you can decrypt the chats using tools like:

  • WhatsApp Viewer

  • WADB Extractor

  • Or Python scripts like whatsapp-decrypt.py

When you decrypt, you will get a file which can be opened using DB Browser for SQLite. It will show full chat history, numbers, time, group messages and everything.

 Where This Is Used

Many people use this knowledge for:

  • Digital forensics

  • Cybercrime investigation

  • Backup and restore

  • Parental control

  • Or just learning how WhatsApp works

But remember — don’t use this on someone else’s phone. It’s only legal when done on your own device or with permission.

 Final Message

My aim is to learn and teach ethical security. I never support misuse. Today hackers are active everywhere. So it’s better to understand how these things work, before someone uses them against us.

Hope you learnt something from this.
Next time I’ll share more tips about mobile forensics or chat timeline analysis.

Take care,
