What is an Initialization Vector? - Definition from …

WebSome encryption algorithms require an initialization vector, which is a randomly generated number that is used along with a secret key to encrypt data. This prevents repeated encryption of the same data using the same secret key. The recipient requires this initialization vector to decrypt the message, and hence, is placed in the JWE token. WebAn initialization vector (IV) is an arbitrary number that can be used with a secret key for data encryption to foil cyber attacks.
