How do I use a ROT13 code?

ROT13 replaces each letter by its partner 13 characters further along the alphabet. For example, HELLO becomes URYYB (or, conversely, URYYB becomes HELLO again).

What is ROT13 encoding?

ROT13 (“rotate by 13 places”, usually hyphenated ROT-13) is a simple Caesar cipher used for obscuring text by replacing each letter with the letter thirteen places down the alphabet.

How do you reverse ROT13?

The easiest way to decrypt is to use the same program used to encrypt the test; ROT13: An offset of 13 allows the encryption to be reversible. The encryption and decryption method are identical. Applying 2 consecutive encryptions (2 shifts of 13) heads to find the original text.

What is Atbash in Atbash?

Atbash is a simple substitution cipher for the Hebrew alphabet. It consists in substituting aleph (the first letter) for tav (the last), beth (the second) for shin (one before last), and so on, reversing the alphabet.

How do I decode Atbash code?

This is a simple cipher to decode. All you need to do is create a translation table with the letters of the alphabet written from A to Z across the top and reversed along the bottom. Find the letter in your cipher text on the bottom row and look above it to see it decrypted.

How do you decode a ROT13 code?

Decoding ROT13 ROT13 is easy to translate without any tools. If you think might be looking at a piece of ROT13 code, all you need to do is to write the letters A-M on a piece of paper, and the letters N to Z below them. You can then substitute the letters accordingly, so if the cipher text has a letter A, the plain text is N and vice versa.

What is a ROT13 cipher?

ROT13 ( rotate by 13 places, sometimes referred to as ROT-13) is a substitution cipher with a shift of 13. That technique substitutes a letter with the 13th letter after it in the alphabet. How to encrypt using Rot13? Encryption with Rot13 substitutes a letter with the 13th letter after it in the English alphabet.

What is the difference between ROT13 and ROT5?

ROT5 is the numeric equivalent of ROT13. The numbers 0-4 are written on the top row, and 5-9 on the bottom. This allows numbers to be encrypted in the same manner as ROT13, by using their inverse. Using ROT13 and ROT5 together is sometimes called ROT18.

Is ROT13 secure for geocaching?

The treasure hunting website, Geocaching.com, uses encrypted hints to the locations of geocaches using ROT13. Although ROT13 is not a secure cipher, it has been used in some commercial applications.
