test the SHA1 of your passwords, not your passwords, and you are safe.
A weak password can still be cracked given the sha1 hash and a dictionary.

#112Also, I'm genuinely curious as to why SHA-1 is used and not SHA-256. Surely the one-time additional cost of using SHA-256 would've been negligible for Troy? If at some point somebody manages to do preimage attacks on SHA-1, I have to assume my password is broken if I've submitted its hash to his API. Although I guess you'd have to actually be able to enumerate preimages, preferably from small to big. Still, I don't understand why Troy doesn't account for the possibility by using a hash function widely considered to be stronger.

#113>If a password is not found in the Pwned Passwords set, it'll result in a response like this: Wait, so I test my password to see if it's "good" and now you have a copy of a password I will be using. Am I just being paranoid?
You can post the sha1sum instead. $ sha1sum SooperSekretPassw0rd^D SooperSekretPassw0rddc0d3504b259a92dce59b850969601d12c06a75f -

Email address is stupid, we should have randomly generated proxy email addresses.
A former coworker makes liberal use of American Express disposable credit card numbers -- proxy credit card numbers that you can request to give away to less than trustworthy merchants.

Privacy ( https://privacy.com/ ) offers a similar service for those that want something that works with more than American Express cards or other such offerings from other card issuers.

KeePass uses an auto-type feature; wouldn't that simulate individual key presses, and defeat anti-paste mechanisms?
I find that on some sites if I click in the username field and alt tab to keepass or any other function I'm suddenly not in the txt field on the site... thus I can't trigger auto type at times.
I then entered {DELAY 3000}{PASSWORD}
Now I can log in to a full screen game that doesn't allow pasting (I type in the username by hand first). If I'm alt-tabbed out of the game with KeePass in focus, the three second delay is enough time to go from triggering auto-type to restoring the full screen game window and clicking on the password field to give it focus. I was unable to trigger KeePass autotype with the game already full screen.
If the account you're trying to log in to also has a long random username that needs to be auto-typed, you'll probably want a sequence like "{DELAY 3000}{USERNAME}{TAB}{PASSWORD}". Or, if the form doesn't allow you to tab from the username to the password field, you could use "{DELAY 3000}{USERNAME}{DELAY 3000}{PASSWORD}" and you can click on the password field during the second delay.

#117For example, if I have a site that requires passwords to be at least 10 chars long, I don't need any of the data for breached passwords that are shorter than 10 characters. People can't possibly use them anyway, so that's probably a huge chunk of the data that's completely useless to be storing and checking.

I believe the idea is to ensure no one can use the listing to brute force.
I think gp is complaining that the second you type your password into the form, you've "used it", hence you should change it. The gp makes a good point, but that's also why you can submit the `sha1($your_password)` instead. The only question is why did Troy allow un-hashed passwords to be submitted.
I mean, here is the SHA1 of my password (not really):

If you're on Windows, you can calculate it in PowerShell like this: $password = "foobar" ([Security.Cryptography.SHA1CryptoServiceProvider]::Create().ComputeHash([Text.Encoding]::ASCII.GetBytes($password)) | %{'{0:x2}' -f $_}) -join ""
