⚡ Key issues to review Possible Bug The loop for checking if a generated key already exists in the database does not wait for the database query to complete due to JavaScript's non-blocking nature. This might result in an infinite loop or incorrect data being inserted into the database. Security Concern The method `decrypt` in `CryptorV1` uses `crypto.createDecipher`, which is deprecated and considered insecure. It should be replaced with `crypto.createDecipheriv` for better security. Error Handling The error handling in the encryption and decryption process does not differentiate between different types of errors (e.g., database errors, encryption errors), which might lead to misleading error messages being shown to the user.
