Minecraft Password Recovery - Decrypt Last Login file - OUTDATED

This is useful if your friend came over and used your computer to play minecraft, and you wanted his password. It can also be used if you have forgotten your own password.

The account I used as an example's password has been changed, dont even try. :P

*UPDATE: You may now download the executable version of this tutorial! You only have to download the newest java version development kit, and then just download this file and run it! (Thanks to: pspm8)
