Answers to Questions (FAQ)
What is the ROT-5 Cipher? (Definition)
The ROT-5 cipher is a simple encryption method that involves shifting each digit 5 positions in 0123456789.
NB: it can also involve shifting letters 5 positions in the alphabet (see ROT cipher).
How to encrypt using Rot5?
How to decrypt Rot-5 cipher?
Decryption of Rot5 is identical to the encryption because Rot5 is reversible.
6789012345
1234567890
Example: 793 re-becomes 248 by ROT-5
How to recognize ROT-5 ciphertext?
ROT-5 converter is used on the digits. Numbers that began with 1 now begin with 6, the 2s become 7s etc. The shifting by 5 continues so on.
According to Benford's law, there should be more 6 than 4 among the first digits of the numbers 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 an alphabet of 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 reciprocal/reversible/symmetric, this means that 2 consecutive encryptions lead to find the plain number.
