Additional information

Understand ROT18

This page intentionally separates two variants. ROT5 + ROT13 applies ROT13 to letters and ROT5 to digits. The ROT18 mode officially applies a rotation of 18 to letters and digits.

ROT5 + ROT13

This mode matches the common usage often called ROT18: letters move forward by 13 positions and digits move forward by 5 positions.

Official ROT18

With a rotation of 18, letters move forward by 18 positions. For digits, the result is equivalent to ROT8 because digits use 10 values: 18 modulo 10 = 8.
