And again about 320 million passwords
Troy Hunt promises that he will not use your password in any way and his service is absolutely reliableAlexanderS : News after a year: “A database with 500 million unique passwords has been published”
Joking as a joke, what if you really check the password without passing it? You can perform a binary search using JS with server queries based on the record number.
320 million passwords fit into 29 requests, and if there is no password in the database, the server will not receive its hash in any way - all the work is done on the client side. But 29 requests take about three seconds. Therefore, you can immediately transfer to the page 2048 hashes covering the first 11 search steps, and each subsequent request will return another 64 hashes, thereby covering six steps at once. Then to check the password you will need only three requests.
They look something like this

This is not very effective in terms of server performance, because 90% of the records given to them are not used, but even a cheap VPS can easily cope with this task.
For the frontend, I found the implementation of sha1 in JS and took the Slate style .
Everything is implemented on one page as simple and primitive as possible, without the use of extraneous things and without putting JS in separate files so that the interested paranoid can personally verify that the script does exactly what it says.
