 #### Padding
-Please note that as of today all input that does not comes as a muptiple of 16 will be padded with zeros to the closest multiple value.
+By default the padding method is `ISO`, however, the class supports:
+```
+ZERO
+PKCS7
+ISO
+```
 
 ### Example
 Sample code using a 128bit key in ECB mode
