Additional information

Understand ROT5

ROT5 is a rotation applied to digits. Each digit moves forward by 5 positions: 0 becomes 5, 1 becomes 6, 5 becomes 0 again, and so on.

Reversible transform

Applying ROT5 a second time cancels the first transformation because digits rotate on a base of 10.

Text preserved

Letters, spaces and punctuation remain visible. The tool is useful for lightly masking numbers without changing the rest of the message.

Related tools

For letters, use ROT13. For digits and letters together, try ROT18.
