+# Diceware
+
+Weak passwords are a big flaw in computer security due to a lack of "entropy" or randomness. For example, how many times have you used the name of a pet or relative or street in a password, or perhaps the number "1". Not very random, is it? :-) Worse still, if passwords are reused between services, that increases your security risk.
+
+Fact is, humans are terrible at remembering random combiations of letters and numbers, but we are great at remembering phrases of words. That's where Diceware comes in.
+
+Diceware is based on the proposal at [http://world.std.com/~reinhold/diceware.html](http://world.std.com/~reinhold/diceware.html) wherein virtual dice are roled 5 times, and the 5 digit number used against a lookup table of words. 4 dice rolls gives you 4 random words which are easy for a human being to remember, yet have a high amount of entropy which makes them hard to crack.
