Novolis.Security.SecureText

Cryptographic device identities and primitives for the Novolis secure-text v1 protocol.

Install

dotnet add package Novolis.Security.SecureText

Guarantees

  • P-256 ECDSA-signed public device bundles.
  • P-256 ECDH pairwise key agreement.
  • HKDF-SHA-256-derived AES-256-GCM conversation keys.
  • A fingerprint that users explicitly compare and pin before accepting a peer.
  • Authenticated ciphertext only; plaintext belongs at the endpoints.

Security model

The relay may observe, retain, replay, delay, drop, or alter envelopes. It must not learn message content or successfully alter a valid message. JWTs and transport TLS control relay access; they do not establish peer cryptographic trust.

Before communication, users compare the full bundle fingerprint through an independent trusted channel and create a SecureTextTrustedPeer. A changed fingerprint blocks delivery until the users repeat this confirmation.

Secure-text v1 uses static, authenticated pairwise ECDH. It does not claim a ratchet, post-compromise security, group messaging, multi-device synchronization, or forward secrecy. Applications requiring those properties must use an audited ratchet protocol rather than extend this package.

Private-key storage

Private keys are exported only so a host can place them in platform-protected storage through ISecureTextKeyStore. Do not write them to configuration, logs, backups, source control, or an ordinary file. Device loss or intentional revocation requires generating a new identity, publishing a new public bundle, and repeating the fingerprint confirmation.

Quick start

using Novolis.Security.SecureText;

var localIdentity = SecureTextDeviceIdentity.Create();
var localBundle = SecureTextPublicBundle.Create(localIdentity);

// Obtain this through the relay, then compare its fingerprint with the peer out of band.
SecureTextPublicBundle peerBundle = GetPeerBundle();
var trustedPeer = new SecureTextTrustedPeer(peerBundle);
trustedPeer.VerifyBundle(peerBundle);

The transport-neutral envelope and replay policy live in Novolis.Messaging.SecureText.
