Args:
data_to_pad (byte string):
The data that needs to be padded.
block_size (integer):
The block boundary to use for padding. The output length is guaranteed
to be a multiple of :data:`block_size`.
style (string):
Padding algorithm. It can be *'pkcs7'* (default), *'iso7816'* or *'x923'*.
Return:
byte string : the original data with the appropriate padding added at the end.

Args:

Padding algorithm. It can be *'pkcs7'* (default), *'iso7816'* or *'x923'*.
