WebJul 12, 2024 · To compare AES-GCM and ChaCha20-Poly1305 for encryption, see above. The longer nonce makes XChaCha20-Poly1305 better suited for long-lived keys (i.e. application-layer cryptography) than AES-GCM. Conclusion: If you’re using the same key for a large number of messages, XChaCha20-Poly1305 has a wider safety margin than AES-GCM.
