Show HN: b2v.xyz – Protection against impersonation attacks Hi HN, I’m the founder of https://b2v.xyz , a service that protects organizations against impersonation attacks. The problem I’m trying to solve stems from the following observation: while end-user authentication methods are becoming more advanced as cybersecurity evolves, organizations aren't experiencing the same improvements when we reverse the roles, i.e. when organizations authenticate themselves to their users. This imbalance leaves a gap in secure communications that B2V aims to close. Bad actors have countless ways to pose as trusted entities — through phishing, smishing, vishing, and more. These catchy terms may sound trendy, but the technology to combat them often lags behind. While some larger companies do offer some customised solutions such as in-app notifications, most approaches are still reactive, such as updating email filters after an attack is detected or requesting takedowns of fake domains long after the damage is done. It's surprising that more proactive measures aren't in place, especially considering the serious consequences of these impersonation attacks. How B2V tackles this problem: - Mutual authentication: During critical communications, an organization can initiate an authentication session and share it with a user via a unique URL. When the user opens it, the organization provides a one-time password that the user can verify. These single-use ephemeral sessions also protect against man-in-the-middle attacks, ensuring that the person you're communicating with is truly who they claim to be. This could also be described as *conversational authentication*. - Digital signatures: Prove the authenticity and integrity of information linked to your organization with public-key cryptography. This is especially useful for verifying that text or links posted on platforms/media outside of your control — such as job boards, paper invoices, forums, or messages — truly come from a trusted entity. For example here's the signature of this post's URL: https://b2v.xyz/b2v_/XHEbx8NdqjTF50?s=https://news.ycombinator.com/item?id=40699265 - Verified online identities: Organizations can link their online identities, similarly to the way Keybase does it. For instance, here's the proof of ownership of this HN account: https://b2v.xyz/b2v_/NMiMMr9KWov6oE?s=hn:b2v - Privacy by design: this system respects your privacy by never tracking or storing plaintext identifying information, only digests and signatures. - For deeper integrations, an API is also available. Could this be useful for machine-to-human or machine-to-machine communications, such as chatbots or multi-agent LLMs? Any feedback would be greatly appreciated, especially about my assumptions! Feel free to check out the docs ( https://docs.b2v.xyz ) and ask me anything. Thanks! https://get.b2v.xyz/ June 17, 2024 at 12:33AM

Show HN: Alpha Demo of NotePad.ai (open source) https://ift.tt/pv7JmUX

Show HN: Alpha Demo of NotePad.ai (open source) Hi all, I threw together a small prototype I am calling “Notepad.ai”. A new take on UIs for interacting with LLMs. While I enjoy using LLM’s in the chat format I wanted to see what it would be like to do it in a more long form style. It let’s you write in a pretty free form, much like Window’s Notepad, but you can choose to hit ctrl+[ to analyze the text with a preset prompt of your choosing. It has a few other small features. It’s WIP and very experimental. I would appreciate any feedback or thoughts.

Show HN: Collate multiple PDFs into one with cover and automatic TOC https://ift.tt/IJs8tGl

Show HN: Collate multiple PDFs into one with cover and automatic TOC collatepdf is a quick-and-dirty Python script I wrote for my own needs to collate multiple PDFs into one (essentially for printing purposes) with the following features: * an optional cover page, * automatic table of contents generation with global page numbering, * automatic page resizing to ensure all pages in the collated PDF have the same dimensions, * an overlay bar on each page with the current file name and global page number. This is alpha-quality software (no tests, minimal documentation etc). Use at your own risks. Hope some will find it useful! https://ift.tt/5lRVI72 June 15, 2024 at 10:29PM

Show HN: I Made a Project Management Software for Freelancers https://ift.tt/kx7usAU

Show HN: I Made a Project Management Software for Freelancers After about 2 months of coding and many late nights I just finished building this simple project management tool that I designed to be specifically for freelancers. Tell me what you think, I am trying to get better at building with NextJS, thank you for any feedback. There is a 10 day free trial if you want to buy it outright. I made this as I didn't like the other tools out there and thought about how the tool could be specialised for freelancers. https://ift.tt/7DJlFhE June 16, 2024 at 12:05AM

Show HN: Summarize Trending GH Repos in Terminal or Browser https://ift.tt/ABrzsV3

Show HN: Summarize Trending GH Repos in Terminal or Browser Hey HN, I built a tool that fetches the daily trending GitHub repositories and uses GPT-4o to generate useful, detailed markdown-style summaries. The app then offers to render them in the terminal itself or as HTML, which is then opened your default web browser. I'm neither a trained programmer nor a computer science student, but I'm a geek nonetheless and had fun building this, so I wanted to share. Maybe it doesn't save anyone any time, but again, I had fun building it. Cheers! https://ift.tt/hmUdlDb June 15, 2024 at 06:53AM

Show HN: 100% open-source voice assistant – as a HAL9000 https://ift.tt/YLGCF8p

Show HN: 100% open-source voice assistant – as a HAL9000 It started in 2018 with my first 3D printer and some openscad designs - just something that looks like a HAL9000 (and had a controlled red LED for the visuals) - it ended up being a full software-project...that hasn't ended yet. But: it is at a (quality-)point at which I am OK with putting it up on stage. My project goals: A digital voice-assistant that is... - actually usable (response times, error rates, ...) - performs everything on-device ("look ma, no cloud") - is entirely Free/Libre Open-Source-Software - is as-easy-as-possible to build I consider all four goals to be accomplished even at this ~90% stage of the project. If you just want to get some quick impressions, check out the "Demos" (video-)page in the github wiki (prominently linked in the README in the github repo). If you want to spend some more time on this, it's probably easiest to watch my presentation at Hackaday Europe from two months ago: https://www.youtube.com/watch?v=oqJCU8FRMQg&t=14761s https://ift.tt/XQMATJ9 June 15, 2024 at 05:57AM
