Hey HN!

Email hasn’t evolved much in decades. It’s still vulnerable to spoofing, surveillance, phishing, and soon quantum attacks.

Secria is a post-quantum secure, privacy-first email service built to fix that. We don’t scan messages. We don’t track users. We don’t store what we don’t need.

Key features:

-Post-quantum encryption by default (ML-KEM)

-One-click alias rotation (easily generate new identities)

-User verification system to prevent impersonation (code swap = trust)

-No tracking pixels, no data collection, no content scanning. Ever.

The idea is simple: privacy and trust, without sacrificing usability. It’s fast, clean, and built for real-world communication.

We’re in early access and shipping fast. Would love your feedback, critiques, or any edge cases you think we’re missing.

We’re two full-time founders, moving quickly and want to be as transparent as possible. AMA.

Where is PQC used? End-to-end or SMTP over TLS (hop-by-hop)? If it is end-to-end, can you easily export a user's public key so they can share it with others?
adrianmav•4h ago
Secria-to-Secria messages are end-to-end encrypted using PQC.

Instead of traditional public key export, we built a simplified system where users can verify each other by exchanging a short code. Under the hood, that code represents a secure identity binding. Effectively a user-friendly way to share public keys and establish trust.

For messages leaving Secria, we fall back to SMTP over TLS, since most of the email world isn’t PQC-ready yet.

We do plan to add traditional public key export as an option for users who want to integrate with other systems but the core trust model is already live via our code-swap mechanism.
