Every network interface have an unique identifier assigned called Media Access Control Address (MAC Address), , used for communication on the physical network segment.


Some weeks ago I started to use Whatsapp Messenger and immediatly I'm worried about how I could  save the messages on media that was less mobile and maybe even a little more durable than a martphone. Searching on the web I found this nice tool that decrypts the encrypted database of WhatsApp and exports all messages in a convenient html file readable with any browser.
