Example: Crypt2.SetEncodedIV method

Demonstrates how to call the SetEncodedIV method. DataFlex

Use ChilkatAx-win32.pkg

Procedure Test
    Handle hoCrypt

    Get Create (RefClass(cComChilkatCrypt2)) To hoCrypt
    If (Not(IsComObjectCreated(hoCrypt))) Begin
        Send CreateComObject of hoCrypt
    End

    Set ComCryptAlgorithm Of hoCrypt To "aes"
    Set ComCipherMode Of hoCrypt To "cbc"
    Set ComKeyLength Of hoCrypt To 256

    // Note: The lenght of the IV is equal to the block size of the symmetric encryption algorithm.
    // The block size for AES is 16 bytes.  Therefore, the IV is 16 bytes regardless of the encryption strenght (128-bit, 256-bit, etc.)
    Send ComSetEncodedIV To hoCrypt "000102030405060708090A0B0C0D0E0F" "hex"

    // ...
    // ...
