An encryption nonce / IV is a constant. Reusing a nonce under the same key breaks the confidentiality and integrity of AES-GCM and ChaCha20-Poly1305 and makes CBC/CTR output predictable.

Category: SECURITY · Engine rule severity: WARNING
How to fix it
Generate a fresh nonce per message (Aes256Gcm::generate_nonce(&mut OsRng) or rand::random) and store it next to the ciphertext.
