PageSigner - a cryptographically secure webpage screenshot tool

Image from store
PageSigner
Description from store

PageSigner allows you to "notarize" web pages. Think of it as a cryptographically secure webpage screenshot - it's different from an ordinary screenshot in that it can't be edited in Photoshop; it really proves that you received that data from the server. You can then share that proof with anyone you like.
PageSigner is an open-source project. You can see the code here:
https://github.com/tlsnotary/pagesigner

Was able to capture a page of reddit. Not all websites produce a useful capture.

The notarization works much faster now!

It didn't work for any of the cases where it matters (financial institution sites, messaging app sites). Often, it seems, if there is a login process, the page it notarizes, if any, has little HTML and doesn't correspond to what I see on the screen. I only had it work for simple cases where preferably there is no login or dynamic content - which renders it largely useless.

Keeps saying that it can only sign https pages even when i click it on https pages.
