QuantumAPI
The European platform for post-quantum encryption & identity
QuantumAPI launched on March 4, 2026.
What it does
Quantum computers will break today's encryption. Adversaries are already harvesting encrypted data to decrypt later. QuantumAPI is the European platform to migrate to post-quantum cryptography: - Encryption-as-a-Service (NIST ML-KEM, ML-DSA) with quantum randomness - Quantum-safe key & secret management - IAM with SSO, OIDC & post-quantum MFA 100% EU-hosted, GDPR & NIS2 compliant. $0 per-seat pricing. SDKs for TypeScript, Python,NET, Rust. Free tier: 500 calls/month.
ML-KEM keeps your data confidential. ML-DSA keeps it verifiable. Keys, tokens and signatures, quantum-safe by default — the sovereign alternative to Okta and 1Password. API keys, passwords, and tokens spread across .env files, Slack messages, and spreadsheets — one leak away from a breach. 100 users = €2,000+/month. Enterprise IAM tools price growing teams out of the market. Schrems II, GDPR, and NIS2 require EU data residency. US-hosted services put you at regulatory risk. RSA and ECC will be broken by quantum computers. NIST standardised replacements in 2024 — most stacks have not caught up. A REST API that encrypts, signs, and verifies with NIST post-quantum algorithms. Drop into any…from quantumapi.eu

- TPTutaCrypt, post-quantum encryption protocols for securing emails [pdf]2024 · tuta.com · ▲15
Hi HN, we are the developers from Tuta (formerly Tutanota), the German end-to-end encrypted email provider, and we recently released the world's first post-quantum encryption for email. We have included a full technical write-up of the cryptography involved in these changes and we have released it for open public review. This document specifies TutaCrypt, a protocol designed for hybrid email encryption in Tuta Mail. The protocol combines a classical Elliptic-Curve-Diffie-Hellman key exchange with a post-quantum KEM. The goal is to replace the usage of RSA in Tuta Mail. In the remainder of…

Talanoa▲346Hi 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…
