Enable AES Padding.
void CL_AES192_Encrypt::set_padding( bool value = true, bool use_pkcs7 = true, unsigned int num_additional_padded_blocks = 0);
Detailed description:
Example (use_pkcs7==true) : ... 0x03 0x03 0x03 (3 octets of padding) Example (use_pkcs7==false) : ... 0x02 0x02 0x02 (3 octets of padding, the last octet is the length)
