Very neat! However, IMHO 63 characters is a bit much for the password.
”If you use lower-case, upper-case, and digits, and if you generate it truly randomly, then a 16-character password has 95 bits of entropy. That is more than sufficient.”

- mikeyouse 7y agoA friend has a ~32 character camel case phrase as his WiFi password.. just a nightmare for people to type on their phones. iOS’s “share pass with contact” helps but every once in awhile someone has to spend 10 minutes trying to get a password to work. So silly.
- prepend 7y agoYour friend needs a guest wifi with “fun friends” as the password that they turn on and off as necessary. It’s funny that friend goes to the effort of a super long password, but then lets people connect to it.
- oefrha 7y agoA 63 character password with ten dictionary words is on average much easier to type than a 16 character random ASCII printable string, especially on phone keyboards.
- Aeolun 7y agoNot on my switch or home entertainment system though.
- Buge 7y agoBut the 10 dictionary words might be less secure than 16 random characters. xkcd estimates a word has 11 bits of entropy.
- oefrha 7y agoYour math is off. Even if you take the 11-bit estimate (if you use something like diceware you get 13 bits), 10 words give you 110 bits. Meanwhile there are 95 ASCII printables, 16 of them give you a maximum of 105 bits, and usually people don’t use the full range (ambiguity, especially painful to type, etc.) & don’t generate a uniformly random string, which means you’re getting fewer than that. Even 95 is an optimistic estimate.
- Buge 7y agoI said "might be", and someone might estimate a word to have 10 bits of entropy. And you previously said dictionary words, not random dictionary words, so a human choosing those words might choose words that relate to each other.
