A documented Android messenger implementing post-quantum key exchange, signatures, and encrypted messaging with NIST-standard algorithms.

Landing page captured for the 2026-09-22 issue.

For: Android and cryptography learners
Worth noticing: Two key-exchange branches expose the difference between a vetted library implementation and a paper-based learning implementation.

Field notes

The project separates a production-oriented branch using BouncyCastle from a deliberately educational branch that implements the Kyber algorithms without a library. Its key-management notes cover message-level rotation, group membership changes, fingerprint checks, and local SQLCipher storage. The author also records important limitations: no external audit, metadata exposure through the server, and side-channel risk in the learning implementation.
