Caesar Cipher FAQs
Common questions about Caesar cipher
What is a Caesar cipher?
A Caesar cipher is a substitution cipher where each letter in the plaintext is shifted a certain number of places down the alphabet. For example, with a shift of 3, A becomes D, B becomes E, etc.
What shift value should I use?
You can use any shift value from 1 to 25. The original Caesar cipher used a shift of 3. Remember to use the same shift value for encoding and decoding.
Is Caesar cipher secure?
No, Caesar cipher is not secure for real encryption. It can be easily broken with frequency analysis or brute force. It is mainly used for educational purposes or simple obfuscation.
