Working with Android
Unencrypted WhatsApp database
Extract the WhatsApp database with whatever means, one possible means is to use the WhatsApp-Key-DB-Extractor
After you obtain your WhatsApp database, copy the WhatsApp database and media folder to the working directory. The database is called msgstore.db. If you also want the name of your contacts, get the contact database, which is called wa.db. And copy the WhatsApp (Media) directory from your phone directly.
And now, you should have something like this in the working directory.
Extracting
Simply invoke the following command from shell.
wtsexporter -a
Enriching Contact from vCard
The default WhatsApp contact database typically contained contact names extracted from your phone, which the exporter used to map your chats. However, in some reported cases, the database may have never been populated. In such case, you can export your contacts to a vCard file from your phone or a cloud provider like Google Contacts. Then, install the necessary dependency and run the following command from the shell:
pip install whatsapp-chat-exporter["vcards"]
wtsexporter -a --enrich-from-vcard contacts.vcf --default-country-code 852
Encrypted Android WhatsApp Backup
In order to support the decryption, install pycryptodome if it is not installed
pip install pycryptodome # Or
pip install whatsapp-chat-exporter["android_backup"] # install along with this software
Tip
Crypt15 is now the easiest way to decrypt a backup. If you have the 32 bytes hex key generated when you enable End-to-End encrypted backup, you can use it to decrypt the backup. If you do not have the 32 bytes hex key, you can still use the key file extracted just like extacting key file for Crypt12 and Crypt14 to decrypt the backup.
Crypt12 or Crypt14
You will need the decryption key file from your phone. If you have root access, you can find it as /data/data/com.whatsapp/files/key. Otherwise, if you used WhatsApp-Key-DB-Extractor before, it will appear in the WhatsApp backup directory as WhatsApp/Databases/.nomedia.
Place the decryption key file (key) and the encrypted WhatsApp Backup (msgstore.db.crypt14) in the working directory. If you also want the name of your contacts, get the contact database, which is called wa.db. And copy the WhatsApp (Media) directory from your phone directly.
And now, you should have something like this in the working directory.
Extracting
Simply invoke the following command from shell.
wtsexporter -a -k key -b msgstore.db.crypt14
Crypt15 (End-to-End Encrypted Backup)
To support Crypt15 backup, install javaobj-py3 if it is not installed
pip install javaobj-py3 # Or
pip install whatsapp-chat-exporter["crypt15"] # install along with this software
Before proceeding with this method, you must first create an end-to-end encrypted backup. For detailed instructions, refer to WhatsApp's help center.
Once you have copied the backup files to your computer, place the encrypted WhatsApp backup file (msgstore.db.crypt15) into the working directory. If you also wish to include your contacts' names, obtain the contact database file, named wa.db. Additionally, copy the WhatsApp Media folder directly from your phone.
If you do not have the 32 bytes hex key (64 hexdigits), place the decryption key file (encrypted_backup.key) extracted from Android. If you gave the 32 bytes hex key, simply put the key in the shell.
Now, you should have something like this in the working directory (if you do not have 32 bytes hex key).
Extracting
If you do not have 32 bytes hex key but have the key file available, simply invoke the following command from shell.
wtsexporter -a -k encrypted_backup.key -b msgstore.db.crypt15
If you have the 32 bytes hex key, simply put the hex key in the -k option and invoke the command from shell like this:
wtsexporter -a -k 432435053b5204b08e5c3823423399aa30ff061435ab89bc4e6713969cdaa5a8 -b msgstore.db.crypt15
