<p>An information processing apparatus includes a processor configured to identify a data length that is longer than a data length of plain text data and that is a multiple of a predetermined block length; calculate a data length difference of the data length of the plain text and the data length; generate a first code that indicates the calculated data length difference; generate a second code that is calculated from the plain text data and is of a data length that is within a remaining data length acquired by subtracting a data length of the generated first code from the data length difference; create padding that includes the generated second code, has the first code at an end, and is of a length equivalent to the data length difference; concatenate the created padding to an end of the plain text data to generate concatenated data; and output the concatenated data.</p> |
