ROT13 is a special case of the Caesar Cipher where each letter of a text is rotated by a shift of 13.  As there are 26 letter the same algorithm to encode the text can be used to retrieve the original text.

The Caesar cipher is a cryptographic technique that involves takes each letter of a text and replacing it by a letter with a set offset. Caesar cipher wheels can be used to code and decode these texts - alternatively you can use the tools above.

The cipher is named after Julius Caesar who is said to have used this method on encryption. Julius Caesar's time in office of the roman empire was in the years 49 to 44BC. It is amazing that even this early we wanted to keep our communication secret.
