IV Property

The initialization vector (IV) used when encrypting.

Syntax

property IV: String read get_IV write set_IV;
property IVB: TBytes read get_IVB write set_IVB;

Default Value

''

Remarks

This property optionally specifies an IV to be used when calling Encrypt or Decrypt. If specified the IV is used by EncryptionAlgorithm during encryption.

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:

This setting is not applicable when EncryptionAlgorithm is set to XOR.
