Yes. The core architecture is crypto-agile. Its foundation is quantum-resistant because it's built on symmetric primitives like hashing and stream ciphers.

We used X25519 and Ed25519 in the transport layer examples for clarity, as they are well-understood, not as a production baseline.

A post-quantum implementation would swap these out. The key exchange would use a hybrid model, combining X25519 with a PQC KEM like CRYSTALS-Kyber. The signature would be replaced with a PQC scheme like CRYSTALS-Dilithium.

This modularity is a fundamental part of the design.

I don’t think this is a public key algorithm, so it’s most likely quantum safe.

Oh, I got excited that there might be a novel approach to asymmetric cryptography.
