Hey PH! 👋 Most post-quantum signing tools are built for one thing: user auth. FIPSign is different — you can sign anything. Users, orders, documents, IoT devices, API tokens. If it has an ID, you can sign it. I built it because RS256/ES256 have an expiry date. NIST finalized the post-quantum replacement (ML-DSA-65, FIPS 204) in August 2024, but there was no simple API to just start using it today. Call /sign and your tokens are quantum-resistant. Use the npm SDK for JS/TS, or hit the REST API directly from any language. No crypto expertise, no infrastructure, no DevOps. Everything is managed from a dashboard — API keys, projects, token usage, 6-month history, webhook config. Runs on Cloudflare's global network (300+ locations). Free tier: 10,000 tokens/month, no credit card. Guide at fipsign.dev/guide — or just create a free account at app.fipsign.dev. I'll be checking in to answer questions — feel free to drop them below. 🚀
