li>Initialization vector a value that is used only once within a specified context. It must be padded to 16-byte length with LSB set to 2.</li>
<li>Key is the parameter which determines the cipher text. In this example the key size is 128 bits =16 bytes but it can be tailored to 192 bits or 256 bits.</li>

<li>Cipher text which is the encryption result of the Plaint text. In this example, the cipher text is available in “EncryptedText”. Its size is the sam
