Hacking whatspp chat i.e. msgstore.db.crypt file

Whatspp saves your chat history locally in a file labelled as msgstore.db.crypt. 
I tried once and after googling I succeeded to crack my own whatsapp chat history.
As I love linux the decryption was a breeze as openssl comes with linux preinstalled. I used the command

 openssl enc -d -aes-192-ecb -in msgstore.db.crypt -out msgstore.db.sqlite -K 346a23652a46392b4d73257c67317e352e3372482177652c

 And I opened the file msgstore.db.sqlite by installing sqliteman through synaptic.
