About Caesar Cipher Tool

Welcome to the online Caesar Cipher Tool! This tool allows you to encrypt and decrypt text using the classic Caesar cipher. The Caesar cipher is a simple substitution cipher where each letter in the plaintext is shifted by a fixed number of positions.

• Simple Shift Cipher: Easily encrypt and decrypt text.
• Custom Shift Value: Choose any shift value for encryption or decryption.
• Case Preservation: Maintains the case of letters.
• Non-Alphabetic Characters: Remain unchanged.

• Learning classical encryption techniques.
• Simple text obfuscation.
• Historical cipher analysis.

• Enter the text you want to process.
• Specify the shift value. For example, a shift of 3 will change A to D, B to E, and so on.
• Select whether to encrypt or decrypt the text.
• Click the button to apply the Caesar cipher.

Example: With a shift of 3, the word HELLO becomes KHOOR when encrypted.

In the Caesar cipher, each letter is shifted a fixed number of positions in the alphabet. The shift wraps around at the end of the alphabet. For example, with a shift of 3, Z would become C.
