This number, also called a nonce (number used once), is employed only one time in any session to prevent unauthorized decryption of the message by a suspicious or malicious actor. INVALID = 0 An invalid data type. Remember that the IV is not secret, but it should still have the properties as described in Squeamish Ossifrage's answer. How to install the previous version of node.js and npm ? For CFB mode, the IV must never be reused for different messages under the same key; for CBC mode, the IV must never be reused for different messages under the same key, and must be unpredictable in advance by an attacker. The length of an encoded vector must be an exact multiple of the length of a single element (e.g., a 17-byte vector of uint16 would be illegal).
