CaesarCipher
Encrypt and decrypt text using Caesar cipher with custom shift
About Caesar Cipher
Named after Julius Caesar, this is one of the oldest encryption techniques. It shifts each letter by a fixed number of positions in the alphabet. Easy to crack but fun for learning cryptography!
💡 Shift of 3: A → D, B → E, etc.
📚 How Caesar Cipher Works
- • Letter Shifting: Each letter is shifted by a fixed number of positions (the key)
- • Example: With shift 3, A→D, B→E, C→F, ..., X→A, Y→B, Z→C
- • Wraparound: Letters wrap around the alphabet (after Z comes A)
- • Case Preserved: Uppercase and lowercase are maintained
- • Non-Letters: Numbers, spaces, and punctuation remain unchanged
- • Brute Force: With only 26 possible keys, it's easy to try them all!
