The initialization vector (IV) used when encrypting.
If not specified the component will create an IV filled with null bytes (zeros). Since the encryption key is only used once the use of null bytes in the IV is considered acceptable and is a standard practice.
The length of the IV should be as follows:
|EncryptionAlgorithm||IV Length (in bytes)|
This setting is not applicable when EncryptionAlgorithm is set to XOR.
