 ## Overview
 Quick Trusted Response (QTR) codes aim to enhance the security and trustworthiness of QR codes by introducing a standardised verification mechanism. By leveraging existing technologies like BIMI (Brand Indicators for Message Identification) and public key cryptography, QTR codes provide a method for users and applications to verify the authenticity of QR code content before any action is taken.

 ## Why QTR Codes?
 - Mitigate QR Code Phishing Attacks: QTR codes help prevent malicious redirection and data theft by verifying the source and integrity of the QR code content.
 - Enhance User Trust: By displaying verified brand logos and validation statuses, users can confidently interact with QR codes.
 - Backward Compatibility: QTR codes are designed to be compatible with existing QR code readers, ensuring a seamless transition.
 
 ## Key Features
 - Signature Verification: Uses cryptographic signatures appended as query parameters to verify content authenticity.
-- Public Key Retrieval: Supports fetching public keys via DNS records or well-known endpoints.
+- Public Key Retrieval: Supports fetching public keys via DNS records, well-known endpoints or HTTP response headers.
 - BIMI Integration: Incorporates BIMI records to display verified brand logos.
 - Offline Validation: Supports caching of BIMI records and public keys for offline verification.
