What kind of moron generates their password on some stranger’s website?I get that. The entropy of a substance is usually given as an intensive property either entropy per unit mass (SI unit: JK 1 kg 1) or entropy per unit amount of substance (SI unit: JK 1 mol 1).

That’s why this page is a singleSelf-contained HTML file with the generator written inA couple hundreds lines of documented, unobfuscatedJavascript. If you like the idea but don’t trustMe, please download this page for your personal use andScrutinize it for yourself to make sure it isn't doingAnything shady. Sometimes, s is used for specific heat capacity in J/g.K qmsT where: q is heat flow in J In is positive and out is. What the is wrong with the length/entropy fields?Entropy is a function of the length and passwordOptions you have chosen, so whenever you change any ofThose values the entropy updates. Entropy Symbol Update The Entropyīut I also let you doIt in reverse, so if you update the entropy it changesThe length needed to get that amount of entropy. What is secure today is not necessarily secure tomorrow.Put all these together and this generator can seemEntirely useless. Claim: If you know the probabilities of symbols in the language, you can compute the average information content of a symbol in the language. But the point of this generator isThat by using the full ASCII range, you get reasonablyShort passwords that are likely to work with whateverService you care to use them with and which areVery unlikely to be the kind of thing anyReasonable password guesser would try. That’s what theEntropy measurement is really getting at.There are password guessers out there that canFeasibly guess a 55 character password but notA fully random ASCII one. Once you pick the password, it’s fixed and no longer random. One example is the concept of corporate entropy as put forward somewhat humorously by authors Tom DeMarco and Timothy Lister in their 1987 classic publication Peopleware, a book on growing and managing productive teams and successful software projects. A password generator has entropy based on the possible passwords it can give you. The term entropy is often used in popular language to denote a variety of unrelated phenomena.
The password generator’s entropy does not measure how hard it is to guess a generated password.
