Summary of Changes

Hello @GareArc, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request implements new decryption decorators for sensitive user input fields within the web application's authentication flows. Specifically, it applies a password decryption decorator to the standard login API and a code decryption decorator to the email code login API, ensuring that these fields are automatically decrypted before being handled by the respective authentication logic. This enhancement aims to bolster the security posture of user authentication by centralizing and automating the decryption process for critical credentials.

Highlights

• New Decryption Decorators: Introduced decrypt_password_field and decrypt_code_field decorators to handle the decryption of sensitive input fields.
• Enhanced Login Security: Applied the new decryption decorators to the post methods of LoginApi and EmailCodeLoginApi to automatically decrypt password and code fields, respectively, before processing.
• Centralized Decryption Logic: This change centralizes the decryption logic for sensitive authentication data, improving maintainability and security.

Code Review

This pull request adds decryption decorators to the password and code fields for web application login endpoints. The changes are correct and achieve the intended goal. However, I've pointed out an architectural concern regarding dependencies between web and console controllers, which could be improved for better modularity and long-term maintainability.
