WhatsApp Viewer cannot natively open .crypt14 files. These files are encrypted WhatsApp databases, and to decrypt them, you typically need both the encryption key and the database file from the same device. Here’s a general guide you could follow:
- Obtain the
msgstore.db.crypt14 file from your device. This is usually located in the WhatsApp/Databases folder on your phone's internal storage.
- You will also need the
key file, which is typically found in the root directory /data/data/com.whatsapp/files/ on a rooted Android device.
- Use a third-party tool like WhatsApp Viewer or a script that can handle decryption using both the .crypt14 file and the
key file.
Please note: Accessing the key file generally requires rooting your device. Be cautious when doing this as it can void warranties and potentially harm the device. Additionally, handling encrypted files might violate WhatsApp's terms of service, so proceed with care and understanding of the legal implications.
