Extension summary
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
Changelog.
v 3.0.6
- update after a server fix v 3.0.5
- fix for large uploads on slow connections v 3.0.4
- allow to preview the notarization without actually running it v 3.0.3
- a better algorithm which is 30% faster and requires 25% less bandwidth
