Frequently Asked Questions
How does the Caesar cipher work?
Each letter is shifted by a fixed number of positions in the alphabet. A shift of 3 makes A become D, B become E, etc.
Can I decode without knowing the shift?
You can try all 25 possible shifts (brute force) to find the correct one.
Is Caesar cipher secure?
No. Caesar cipher is trivially broken with brute force (only 25 possibilities) or frequency analysis.
