//! Transport Layer Security (TLS 1.2 / TLS 1.3) (RFC 8446 (TLS 1.3) / RFC 5246 (TLS 1.2) / RFC 6066 (SNI) / RFC 7301 (ALPN)) Layer 7 AST definitions.
//!
//! This module defines the abstract syntax tree (AST) configuration parameters for synthesizing
//! Transport Layer Security (TLS 1.2 / TLS 1.3) packets over TCP port 443. On the wire, the protocol uses a 5-byte TLS Record Layer header (8-bit ContentType: `21` Alert, `22` Handshake, `23` ApplicationData; 16-bit Legacy Record Version e.g. `0x0303`; 16-bit Length) encapsulating a 4-byte Handshake header (8-bit HandshakeType: `1` ClientHello, `2` ServerHello, `11` Certificate, `20` Finished; 24-bit Length), 32-byte Random nonce, CipherSuite list (`0x1301` TLS_AES_128_GCM_SHA256, `0x1302` TLS_AES_256_GCM_SHA384), and SNI (`0x0000`) / ALPN (`0x0010`) extensions.
//! Every field in [`TlsSpec`] is optional so authors can emit zero-configuration default
//! frames or override specific protocol header fields and attributes.
//!
//! Canonical `.fasm` syntax:
//! `a -> b TLS [CLIENT_HELLO | SERVER_HELLO | CERTIFICATE | FINISHED | APP_DATA | ALERT] [RECORD_VERSION <u16>] [HANDSHAKE_VERSION <u16>] [SNI <str>] [CIPHERSUITE <u16>] [ALPN <str>]`
