Potential fix for code scanning alert no. 15: Clear text storage of sensitive information

[KDust7]

Potential fix for https://github.com/NightProxy/Space/security/code-scanning/15

To fix the problem, we need to ensure that the key binding value is encrypted before being stored in localStorage. We can use the Node.js crypto module to encrypt the value. The decryption should be done when retrieving the value from localStorage.

1. Import the crypto module.
2. Define encryption and decryption functions.
3. Encrypt the key binding value before storing it in localStorage.
4. Decrypt the key binding value when retrieving it from localStorage.
