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
