Post-Quantum Identity + Messaging

A practical successor to PGP, built for the next era of cryptography.

EBP pairs modern post-quantum signing and encryption into one simple-to-use identity management tool.

Why EBP

Post-Quantum by Design

Built on NIST-approved quantum-resistant algorithms (ML-DSA, SLH-DSA, ML-KEM) at Security Category 5 — not retrofitted onto legacy PGP assumptions.

Identity-Centered Security

Your identity pairs a signing key with an encryption key under one fingerprint — easy to share, easy to verify, impossible to confuse.

Real-World Controls

Revoke individual details or entire identities with signed certificates. Pre-generate emergency revocation keys for compromise scenarios, with replay-attack protection built in.

How It Works

  1. Generate an identity (signing key + encryption key).
  2. Share your public identity and fingerprint.
  3. Import contacts, then sign/verify and encrypt/decrypt messages.
  4. Use the built-in email tools to sign, encrypt, decrypt, and verify messages.
  5. Revoke details or full identities if trust changes.

Build trust that can adapt.

We believe it is important to build a flexible, adaptive post-quantum standard early so adoption can converge instead of fragment. A world where people agree on crypto standards is safer for everyone. We welcome contributions and collaboration — it should be easier to join us than compete with us.
