Crate phantom_protocol 

Phantom Protocol SDK

Post-quantum secure L4/L6 universal transport framework.

Provides:

• Hybrid key exchange (X25519 + ML-KEM-768; X-Wing-style combiner). Under --features fips the classical half swaps to ECDH-P-256.
• Hybrid signatures (Ed25519 + ML-DSA-65) — both halves must verify.
• PhantomUDP, a native reliable transport over raw UDP (the production transport), plus byte-pipe SessionTransport impls for TCP, browser WebSocket, WASI, embedded UART/USB, and an off-by-default TLS-mimicry leg.
• Seamless single-path connection migration (not multipath aggregation — that was deliberately rejected) with liveness detection and keep-alive PINGs.
• Stream multiplexing (reliable + unreliable).

The core transmits only Vec<u8> / Bytes. Serialization (JSON, Protobuf, etc.) is the user’s responsibility.
