Module tls_extensions 

TLS Extensions for RFC 7250 certificate type negotiation TLS Extensions for RFC 7250 Raw Public Keys Certificate Type Negotiation

This module implements the TLS 1.3 extensions defined in RFC 7250 Section 4.2:

• client_certificate_type (47): Client’s certificate type preferences
• server_certificate_type (48): Server’s certificate type preferences

These extensions enable proper negotiation of certificate types during TLS handshake, allowing clients and servers to indicate support for Raw Public Keys (value 2) in addition to traditional X.509 certificates (value 0).
