A cipher is initialised with a constant IV/nonce. Reusing an IV/nonce with the same key breaks confidentiality (and integrity for GCM/CTR).
Category: SECURITY · Engine rule severity: WARNING
How to fix it
Generate a fresh IV/nonce per message with os.urandom() / secrets.token_bytes() and store it with the ciphertext.
