-            <strong>Hight ECB Cipher Information</strong><br>
-            - The user input for the key should be 128 bit and in hexadecimal format.<br>
-            - The user input for plaintext or ciphertext can be of any length, both greater than or less than 64 bits, and in hexadecimal format.<br>
-            - A padding block has been added to ever plaintext encryption.<br>
-            - Padding scheme used for this block cipher is “OneAndZeroes Padding”.

-          <p>
-            <strong>Hexadecimal Value Input</strong><br>
-            Hexadecimal values can be input with or without spaces between the characters.<br>
