PageSigner - a cryptographically secure webpage screenshot tool

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:
