we all know that Caeasar Cipher accepts only alphabets from A-Z and its key is n<=26.

Caesar Cipher does not accept numbers.

last night , I found an exercise which said that this code a certain code is encoded using Caesar Cipher **BUT** this code is a **composed of numbers and alphabets** like for example "69bc". This surprised me because as I said :" **Caesar Cipher does not accept numbers**" but I see a code with numbers and not only alphabets and this code must be decrypted to plain text.

the solution does not interest me . I am very very interested on and my questions are :

**2)how a code, which is composed from numbers and alphabets, is created using Caesar Cipher encoding???

1)how to decrypt a code (which is encoded using Ceasar Cipher and composed not only from alphabets but numbers like for example "69dc" )if we know that Cisaer Cipher does not accept numbers????????

**

any help would be appreciated
