IV Property
The initialization vector (IV) used when encrypting.
Syntax
ecccontrol.IV[=string]
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 control 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) |
| AES | 16 |
| 3DES | 8 |
This setting is not applicable when EncryptionAlgorithm is set to XOR.
To read or write binary data to the property, a Variant (Byte Array) version is provided in .IVB.
Data Type
Binary String
