How to Decrypt WhatsApp crypt7 Database Messages:

(commands below are run from a linux enviroment)

1. Extract Key File: /data/data/com.whatsapp/files/key
   
2. Extract crypt7 file: /sdcard/WhatsApp/Databases/msgstore.db.crypt7
   
3. Extract Decryption Keys from "key" file extracted in step 1:
   

   256-bit AES key:
   
   hexdump -e '2/1 "%02x"' key | cut -b 253-316 > aes.txt
   
   IV (initialisation vector):
   
   hexdump -e '2/1 "%02x"' key | cut -b 221-252 > iv.txt

   
   

4. Strip Header in crypt7 File:
   

   dd if=msgstore.db.crypt7 of=msgstore.db.crypt7.nohdr ibs=67 skip=1
   
   Note: Size of header stripped file in bytes must be divisible by 16

   
   

5. Decrypt crypt7 File:
   

   openssl enc -aes-256-cbc -d -nosalt -nopad -bufsize 16384 -in msgstore.db.crypt7.nohdr -K $(cat aes.txt) -iv $(cat iv.txt) > msgstore.db

Nu ai cum sa decriptezi fara key. Acolo se afla informatiile necesare pentru a decripta AES.
