According to this article the files with the .db.crypt extension uses a 192 bits AES key whose value is 346a23652a46392b4d73257c67317e352e3372482177652c .

To decrypt you can use OpenSSL that is preinstalled on Linux, Windows can be downloaded here > .

To decrypt you can use the shell-script below.

#!/bin/sh
openssl enc -d -aes-192-ecb \
    -in "$1" -out "$2" \
    -K 346a23652a46392b4d73257c67317e352e3372482177652c

To use it just call:

~$ NomeDoScript.sh msgstore.db.crypt msgstore.db

Returning to the subject of the question, in Github there is a project called whassup that does exactly what you want, in that < a href="https://github.com/jberkel/whassup/blob/master/library/src/main/java/com/github/jberkel/whassup/crypto/DBDecryptor.java"> page (< in> DBDecryptor.java ) you can see the routine responsible for encrypting and decrypting messages.
