Summary of Changes

Hello @fatelei, 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 addresses a critical security concern by ensuring that sensitive API keys are properly obfuscated before being included in HTTP request headers. By integrating an encrypter utility, the change prevents API keys from being exposed in plain text, significantly improving the application's security posture during HTTP requests.

Highlights

• API Key Obfuscation: Implemented obfuscation for API keys across different authentication types (Bearer, Basic, Custom) within HTTP request headers to enhance security.

Code Review

This pull request aims to fix an issue with API key obfuscation. However, the current implementation incorrectly applies obfuscation to the API key for all outgoing HTTP requests, not just for logging. This is a critical issue as it will cause authentication to fail for any request using API key authentication. I've provided a comment with a detailed explanation and a suggestion to revert the change and apply the obfuscation logic only within the logging functionality.
