Module tls 

TLS (Transport Layer Security) protocol layer.

Implements parsing and building for the TLS record protocol (RFC 5246, RFC 8446), including support for SSLv2, TLS 1.0-1.2, and TLS 1.3.

This is a “clean-sheet” implementation that follows Scapy’s “Permissive Parser, Explicit Builder” pattern, allowing construction of malformed packets for security research and fuzzing.

Record Format

ContentType  type;           // 1 byte (20-24)
ProtocolVersion version;     // 2 bytes
uint16 length;               // 2 bytes
opaque fragment[length];     // variable
