Tool to decrypt/encrypt with rot5. ROT-5 is an application of ROT-13 to the numbers, the shift of 5 makes the cipher reversible for numbers.

Answers to Questions

How to encrypt using Rot5?

Rot 5 applies on the numbers in a message. It involves replacing a digit by another by adding 5 (modulo 10).

Example: 1234567890 6789012345

Example: 248 is crypted 793 by ROT-5

How to decrypt Rot-13 cipher?

Decryption of Rot5 is identical to the encryption because Rot5 is reversible.

Example: 1234567890 6789012345

Example: 793 re-becomes 248.

How to recognize ROT-5 ciphertext?

ROT-5 is used on the digits. Numbers that began with 1 now begin with 6 etc.

According to Benford's law, there should be more 6 than 4 in the ciphertext.

What are the variants of the Rot-5 cipher?

Rot-5 is already a variant of Rot13, itself a version of Caesar cipher with a shift of 13. Rot-5 is therefore a Caesar cipher with a shift of 5, but applied to the digits.

It is common to associate a ROT-13 for coding the letters and ROT-5 for the numbers at the same time.

What a shift of 5 for Rot5?

A shift of 5 allows the code to be reciproqual, this means that 2 consecutive encryptions lead to find the original number.
