Text Encrypt / Decrypt – Simple Cipher

This tool applies a simple cipher to encrypt or decrypt text. It is designed for basic obfuscation, quick text hiding and educational purposes, not for strong cryptographic security.

How to Use

  1. Paste the text you want to encrypt or decrypt.
  2. Choose the mode: Encrypt or Decrypt.
  3. Enter a key or shift value if required.
  4. Click the button and copy the result.

Use Cases

  • Hiding spoilers or simple notes.
  • Educational experiments with basic ciphers.
  • Non-critical obfuscation in text samples.

FAQ

Is this strong encryption?

No. It uses a simple cipher and is not suitable for sensitive or confidential data.

Do I need to remember the key?

Yes, you need the same key or shift value to decrypt what was encrypted.
