06. Dec 2010		Quite fun, i liked the junk code, messing around with the head, keygen soon, but i think i will pass on the tutorial, this is more about avoidance of junk code rather than algo, it's just nicely wrapped with shit that you don't need:

run keygenme with parametr:
71B5E113A5D75DB442D4C7D07B384DBD8431F9027C192274F7FD2EFA005776C460D2FE81845AF4DDAFEDB6CDB006573E79609807620AD1085CD86389822D6FD6

this will register keygenme to:
licensed name=tamaroth
sn=666
featureset=fffff
expiration=12123999

cheers
