Some have taken the Atbash technique and mixed it with the Caesar technique. One might think that breaking such a cipher technique would be hard. With the aid of digital computers today, such a cipher could be broken within seconds on your home PC by a brute force attack. How could a monoalphabetic substitution be solved if we do not know whether the cipher alphabet is atbash, caesar, some combination of the two or just random? This is addressed in the monoalphabetic substitution section.
