The initialization vector (IV).
This property specifies the initialization vector (IV). This is also referred to as the nonce. By default this property is empty and the component will automatically generate a new IV value if KeyPassword or Key is set before Encrypt or EncryptBlock is called.
When Algorithm is set to XSalsa the length of the IV must be 192 bits in length (24 bytes).
When Algorithm is set to Salsa the length of the IV must be 64 bits in length (8 bytes).
