How to check encryption in WhatsApp - in detail?

To ensure that your conversations on WhatsApp are encrypted, you can follow several detailed steps. WhatsApp uses end-to-end encryption by default for all messages and calls, meaning only the sender and receiver can read or listen to them. Here’s how to verify this encryption:

1. Checking Message Encryption:

   • Open WhatsApp and navigate to any chat.
   • Tap on the contact's name at the top of the screen to open their profile information.
   • Look for a lock icon next to the contact’s name. This indicates that the messages are end-to-end encrypted. If you don't see this icon, it may be because your WhatsApp version is outdated or there might be an issue with encryption due to technical problems.

2. Verifying Encryption in Groups:

   • Open any group chat.
   • Tap on the group name at the top of the screen.
   • Look for a lock icon next to the group name. This signifies that the messages within this group are also end-to-end encrypted.

3. Call Encryption:

   • WhatsApp calls, including voice and video, are also end-to-end encrypted by default.
   • To ensure encryption during a call, look for a lock icon in the top left corner of your screen while you are on the call. This confirms that the call is securely encrypted.

4. Security Code:

   • You can compare security codes with the person you’re communicating with to verify that your messages and calls are end-to-end encrypted.
   • Open any chat, then tap on the contact's name at the top of the screen.
   • Tap "Encryption" and you will see a 60-digit number. This is your security code.
   • Ask the other person to do the same and compare the last few digits (e.g., the last eight digits). If they match, it means your messages and calls with that contact are end-to-end encrypted.

5. Updating WhatsApp:

   • Ensure you have the latest version of WhatsApp installed. Updates often include security improvements and new features related to encryption.
   • You can check for updates in your device’s app store.

By following these steps, you can confidently verify that your communications on WhatsApp are securely encrypted, providing peace of mind that your conversations remain private.
