FIPSign

What it does

JWT and ECDSA will be broken by quantum computers. Nation-states are already harvesting signed traffic today. FIPSign is a signing API built on ML-DSA-65 (NIST FIPS 204). Call /sign, get a quantum-resistant token. No infra, no DevOps, no keys to manage. Sign users, orders, documents, IoT devices — anything with a sub field. Free tier: 10,000 tokens/month, revocation, offline verification, webhooks, REST API + npm SDK. No credit card. No sales call. Production-ready in 5 minutes.

The post-quantum security suite for developers and enterprises. Sign anything with ML-DSA-44, ML-DSA-65, or ML-DSA-87 — choose your security level per project. Proxy everything with X25519MLKEM768. No cryptography expertise required.

Two products. No cryptography expertise required. Sign anything. Proxy everything. Protected against quantum threats — today. FIPSign covers the two layers that matter most: what you sign and how you transmit it. Post-quantum signing as a service. Sign tokens, issue certificates, and verify identities — choose ML-DSA-44, ML-DSA-65, or ML-DSA-87 per project. No key management, no infrastructure. Get an API key and call /sign in minutes. Post-quantum TLS reverse proxy — available as a managed cloud service or self-hosted on your own server. Every connection is automatically protected with X25519MLKEM768. No code changes to your backend. Both products implement NIST-standardized post-quantum…from fipsign.dev

  Free Quantum-Resistant Timestamping API (Dual-Signature and Bitcoin)Nov 2025 · ▲5

  SasaSavic.ca recently launched a public cryptographic timestamping service designed to remain verifiable even in a post-quantum world. The platform uses SasaSavic Quantum Shield™, a dual-signature protocol combining classical and post-quantum security. Each submitted SHA-256 hash is: • Dual-signed with ECDSA P-256 and ML-DSA-65 (per NIST FIPS 204) • Anchored to the Bitcoin blockchain via OpenTimestamps • Recorded in a public, verifiable daily ledger API (beta, no auth required): https://sasasavic.ca/beta-api/ Example curl request: curl -X POST…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
