The ROT47 cipher method uses the Vigenere method, the only difference being that the key should be numeric, so no need to calculate the rank of the letters of the key in the alphabet. The ROT47 cipher method is a variant created by Count ROT47, it is similar to the Vigenere cipher except that it uses just 10 different cipher alphabets, corresponding to the digits 0 to 9.
Eg Plain text : abcdefghi
Key : 123456
Ciphered text : bdfhjlhjl
