# Post-quantum does not mean science fiction. It means thinking about how long your secrets will last.

The future can preserve what it intercepts today

Encrypted content can be collected today and attacked in the future. Layergram v3 uses a hybrid approach to reduce this risk, without promising the impossible.

## Intercept and store

An observer can store encrypted data without being able to read it now.

## Attack with new tools

The value of the secret depends on how long it must remain secret.

## Hybrid approach

LMF v3 combines a classical and a post-quantum component for identity and conversation initiation. The goal is not to depend on a single family of mathematical problems.

## Forward Secrecy

The state of the conversation evolves. Compromising a current key does not automatically open all previous history.

## No absolute promises

Post-quantum does not mean inviolable or safe forever. Implementation, devices, testing and new discoveries remain essential.

## Explicit migration

A new identity v3 requires new exchange and verification. Layergram doesn't pretend that a prior trust relationship migrates silently.
