Algorithm. GenerateIV Method
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
When overridden in a derived class, generates a random initialization vector (IV) to use for the algorithm.
public: abstract void GenerateIV();
public abstract void GenerateIV ();
abstract member GenerateIV : unit -> unit
Public MustOverride Sub GenerateIV ()
In general, there is no reason to use this method, because
CreateEncryptor(null, null) automatically generates both an initialization vector and a key. However, you may want to use the GenerateIV method to reuse a symmetric algorithm instance with a different initialization vector.
