Clear text consists of the following18 bytes:
F14ADBDA019D6DB7 EFD91546E3FF8444 9BCB
In
order to make this a multiple of 16 bytes (the AES block size), we
must add 14 bytes. Each byte will contain the value 0x0E, which is
14, the total number of padding bytes added. The result is that the
padded clear text is as follows:
F14ADBDA019D6DB7 EFD91546E3FF8444 9BCB0E0E0E0E0E0E
0E0E0E0E0E0E0E0E
The padded value is 32 bytes in length, which
is two AES blocks. This padded string is encrypted in CBC mode, and
the resulting ciphertext will also be 32 bytes in length.
