Need to encode letters too?
Use ROT18 to apply ROT13 to letters and ROT5 to digits in the same operation.
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.
