Show HN: Mailwitness – Digital Signatures over Email https://ift.tt/snqe276

Show HN: Mailwitness – Digital Signatures over Email Hi HN, I'm Marek Dopiera and I wanted to share the digital signature solution which I made with my software house. Your feedback would be much appreciated. We've just launched it - it's a service for signing documents over e-mail - https://mailwitness.com . It still has some rough edges, but hopefully it is useful already. To sign a PDF with somebody, you e-mail them the PDF and put sign@mailwitness.com in CC. If they agree, they need to forward it to sign@mailwitness.com. When they do, you all get your document signed. You can generate PDFs from e-mail, too for convenience. We made this to raise the safety bar of agreements made via e-mail. Via anecdotal evidence, we know that if people do not use services like DocuSign or HelloSign, they consider an e-mail conversation as proof or they print, sign and scan documents. I think we're offering more safety and convenience, because we're preventing the documents from alteration, forging fakes and backdating (by using OpenTimestamp, which essentially constructs a Merkle tree and puts its root into a Bitcoin transaction). I'm hoping that our service becomes useful also because it doesn't require any sign-up (just one confirmation e-mail for Ts&Cs), it's free (in the basic model) and doesn't require the extra cognitive load on learning a web app or a mobile app. You may argue, that one can create a fake e-mail account and use that. That's a valid point, but the reality proves that verification via e-mail is enough for lots of people (vide the agreements over e-mail or DocuSign or HelloSign). In the future we may create paid options, which would include extra identity verification. Even without that extra option, things are not as bad, though: if you use your work e-mail, it's usually your employer who verified your identity. Another question you might have is spoofing. If your e-mail has a valid DKIM signature (which is the case for most major e-mail providers), we'll accept your message. If it doesn't we'll send you a message to verify that you can also receive e-mail. For data safety, we have designed the service such that we discard the documents as soon as we process an e-mail (usually a low number of seconds). Finally, there is legal safety. We operate under the EU law, which qualifies us as a "Trust service provider" and puts requirements on our service. What we do, qualifies as an "Advanced Digital Signature" and according to the EU law, cannot be denied legal effect based on the grounds that it is digital. Monetization path is unclear yet - I want to see if this catches on and if yes, how people are going to use it. Some options include extra services like using your own certificate rather than ours or identity verification. I would really love to hear your feedback - especially for what reasons you would not use it. Thank you https://mailwitness.com March 4, 2022 at 11:26PM

Show HN: WAPM – WebAssembly Package Manager https://ift.tt/N4LsAyU

Show HN: WAPM – WebAssembly Package Manager Hi HN! I’m Syrus, from the Wasmer team. We just released the new version of WAPM that is an order of magnitude better than the previous one (that we also announced here in HN two years ago! [0]), enabling an incredible experience for using and publishing WebAssembly packages. The tech stack that we are using includes: * Python and Django (for the backend) with Graphene (for the open GraphQL API [1]) and Django Channels with websockets over GraphQL [2] for subscriptions * Next.js [3] with React-Relay [4] and Tailwind.css [5] for the frontend * WebAssembly and Wasmer [6] (for the online shell) Vercel for serving the frontend and GCP for serving the backend. Please let me know if you have any questions, I’d be very happy to answer them! https://wapm.io/ March 3, 2022 at 12:52AM

Show HN: I made a WebGL-based app that traces images using circles https://ift.tt/joJLwN7

Show HN: I made a WebGL-based app that traces images using circles I was fascinated by this [0] and this video [1]. After many struggles, I finally built this app that traces images using circles similar to what these videos had shown. The most challenging part (to me) is to find a way to convert images to vector lines. I had tried Potrace, but its output is not suitable for my use case: too many small elements share the same border. Potrace's goal is to represent the original image faithfully using vector lines. But I want to trace the image edges. After searching and trying some Potrace alternatives in vain, I finally found my keyword. Surprisingly (to me), it lies at the end of the wiki page of the very topic [2]. Then I found a paper [3] that has nice pseudocode and a C implementation. I rewrote the pseudocode in Rust because I wanted to experiment with rustwasm. Honestly, I didn't care much about the math behind it. From then, I could continue to finish the app and show it to the world. This app is also my chance to learn about rustwasm and WebGL. FYI: this app is offline-only; your images never leave your browser [0] https://www.youtube.com/watch?v=r6sGWTCMz2k [1] https://www.youtube.com/watch?v=-qgreAUpPwM [2] https://ift.tt/Pro6wkp [3] https://ift.tt/qeYthsw https://ift.tt/ugedaB4 March 2, 2022 at 11:26PM
