JavaScript encryption and decryption tool function description

Core function:
1. JS code encryption： JavaScript code will be converted to an encrypted form based on the eval method, effectively hiding the original logic, enhance code security.
2. JS code decryption： Restore the code encrypted by eval method, easy to debug or learn the encrypted script.
3. Instant Operation： All processing is done locally in the browser, no need to upload to the server to protect data privacy.

Usage

1. Encryption：
- Paste the encrypted JS code in the input box.
- Click the "Encrypt" button, the system automatically generates the eval encryption code.
- Copy the result and apply it to your project.
2. Decryption：
- Input the encrypted eval code snippet.
- Click the "Decrypt" button to restore the original code.

Scenarios

- Protecting front-end code logic from being easily analysed or tampered with.
- Debugging third-party encryption scripts to quickly understand their implementation principles.
- Demonstrate the encryption and decryption mechanism of the eval method.
Notes:
• This tool is suitable for regular JS code encryption and decryption, complex obfuscated code may require additional processing.
• It is recommended to test the integrity of the function after encryption to avoid abnormalities caused by syntax conflicts.
• Long-term storage of sensitive information still need to be combined with the back-end encryption scheme.
