Times ago, I was reading something on numerical systems and password generators and I find myself discovering Diceware, a system for generating a passphrase using several 6-side dice. I think it was funny, so I looked for some dice in my house to try the system. Unfortunately, I have just one d6. Diceware requires five throws just for a single word and a good passphrase requires 3 or 4 words, plus some modifiers here and there. In total, I should throw that single die 20 times to get a good passphrase.
