Projects

  1. HollowLock

    A local tool that runs real TLS 1.3 handshakes against a domain and reports whether its post-quantum key exchange is enforced, merely available, or absent, with a cryptographic bill of materials and a signed PDF report.

    Python Infrastructure security

  2. Kestrel

    Static detection of ML-KEM and ML-DSA inside stripped, statically linked and obfuscated binaries, by fingerprinting the number-theoretic transform constant tables the algorithms cannot run without.

    Python (standard library only) Cryptographic migration

  3. Quantum Cloud Guard

    A software-only, three-layer architecture for small and medium-sized enterprises: client-side hybrid post-quantum encryption, self-hosted key custody with ML-DSA-87-signed keys, and an application-layer abuse gateway.
