Crypto Stack

All crypto from lux/crypto - one implementation, all platforms:

Algorithm	Purpose	NIST Level
ML-DSA-65	Signatures	Level 3
ML-KEM-768	Key Encapsulation	Level 3
Ringtail	PQ Threshold Sigs	Ring-LWE
BLS12-381	Consensus	-
XChaCha20-Poly1305	AEAD	-
Blake2b/Blake3	Hashing	-

GPU acceleration via GPU with custom Metal (macOS/iOS) and CUDA (Linux) kernels.

Session IDs

Pars uses "07" prefix for post-quantum session IDs:

07 + hex(Blake2b-256(ML-KEM-768_pk || ML-DSA-65_pk))

Legacy Session IDs use "05" prefix (X25519/Ed25519).
