Fri, 10 Apr 2026 00:00:00 GMT https://conordeegan.dev/blog/ml-kem-ml-dsa-what-is-a-secret-key The seed is the secret key. The expanded key is a cache. Tue, 17 Mar 2026 00:00:00 GMT https://conordeegan.dev/blog/ml-dsa-pre-hash-or-pure An overcomplicated way to do something that is already simple. Tue, 24 Feb 2026 00:00:00 GMT https://conordeegan.dev/blog/post-quantum-signatures-part-3 Reusing a Lamport key compromises security. This post shows how an attacker can recover the entire private key and forge signatures on arbitrary messages. Tue, 17 Feb 2026 00:00:00 GMT https://conordeegan.dev/blog/post-quantum-signatures-part-2 Lamport signatures are post-quantum signatures buuld entirely on the properties of the hash function. This post builds them from scratch in Rust. Mon, 16 Feb 2026 00:00:00 GMT https://conordeegan.dev/blog/post-quantum-signatures-part-1 SHA-256 is the foundation of post-quantum signatures. This post builds it from scratch in Rust. Sun, 15 Feb 2026 00:00:00 GMT https://conordeegan.dev/blog/x-wing X-Wing is a hybrid KEM that doesn\'t make you pay a performance penalty for the safety.

Tue, 03 Feb 2026 00:00:00 GMT https://conordeegan.dev/blog/pqc-and-side-channels The gap between standards and implementations is a problem for PQC. Mon, 26 Jan 2026 00:00:00 GMT https://conordeegan.dev/blog/quantum-is-not-only-decryption-it-is-forgery-too Quantum is not only a confidentiality problem, it is an authenticity problem too. Tue, 20 Jan 2026 00:00:00 GMT https://conordeegan.dev/blog/the-post-quantum-signature-trilemma A way to think about the structural trade-off in post-quantum signatures. Mon, 12 Jan 2026 00:00:00 GMT https://conordeegan.dev/blog/the-shared-discipline-of-security-engineering Thinking about the shared discipline of security engineering and how we should think about security as we scale. Mon, 22 Dec 2025 00:00:00 GMT https://conordeegan.dev/blog/creating-a-blake3-variant-to-slh-dsa Some notes on creating a BLAKE3 variant of SLH-DSA Fri, 07 Nov 2025 00:00:00 GMT https://conordeegan.dev/blog/replacing-shake-with-blake3-in-ml-dsa Some notes on replacing SHAKE with BLAKE3 in ML-DSA Thu, 09 Oct 2025 00:00:00 GMT https://conordeegan.dev/blog/benchmarking-post-quantum Some notes on benchmarking post-quantum signatures against ECDSA Sun, 13 Jul 2025 00:00:00 GMT https://conordeegan.dev/blog/hybrid-pqc My thoughts on approaching the migration to hybrid post-quantum cryptography and beyond. Wed, 09 Apr 2025 00:00:00 GMT https://conordeegan.dev/blog/what-is-quantum-computing A guest post I wrote for the Technically.dev blog Tue, 28 Jan 2025 00:00:00 GMT https://conordeegan.dev/blog/qc-openness Thinking about the ethical implications of quantum computing and how best to ensure that the technology is used for the greater good.
