Caesar Cipher
A simple substitution cipher for text.
About the Caesar Cipher
The Caesar cipher is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. For example, with a left shift of 3, 'D' would be replaced by 'A'. This tool allows you to both encrypt and decrypt messages using this classic method, making it a fun way to learn about the basics of cryptography.
How to Use This Tool
- Enter Text: Type or paste the message you want to work with into the main text area.
- Set Shift Amount: Enter a number between 0 and 25 in the "Shift Amount" field. This is the key for the cipher.
- Encrypt or Decrypt: Click "Encrypt" to shift the letters forward, or "Decrypt" to shift them backward.
- View Result: The transformed message will appear in the "Result" box.
