Guide to Caesar Cipher Decryption
Understanding Decryption
Decryption is the reverse process of Caesar cipher encryption. While encryption shifts letters forward in the alphabet, decryption shifts them backward by the same amount to recover the original message.
How to Decrypt
- Enter the encrypted text in the input field
- Select the same alphabet type used for encryption
- Enter the same shift amount used during encryption
- Match the case and space preservation settings
- The decrypted text will appear automatically (in live mode)
Tips for Successful Decryption
- Ensure you know the correct shift value
- Match the alphabet settings with the encryption
- Preserve formatting if the original text had special formatting
- Use the same case sensitivity settings as encryption
Troubleshooting
If decryption produces unexpected results:
- Verify the shift amount matches the encryption
- Check if the correct alphabet type is selected
- Ensure the text was actually encrypted using Caesar cipher
- Look for any special characters that might affect decryption
