01 02 Only 1 of 24 U.S. agencies has a complete inventory of quantum-vulnerable crypto, because counting is apparently optional.03 Can you prove a site's AI training opt-in/opt-out without leaking the declaration? MachineWitness batches it into daily Merkle roots.04 Unsovled Napoleonic homophonic cipher finally falls, with the key recovered and the plaintext checked against the letter.05 PQC triage tool, not just an inventory, it ranks call sites by quantum breakage risk and emits an audit trail plus migration plan.06 Paper on R statistical modeling with FHE via openfhe.R/homomorpheR, from Cox regression to similarity search, because plaintext is overra...07 Why can't you just brute-force an iPhone passcode? The Secure Enclave adds hardware keys, delays, and lockouts.08 7.5x faster ChaCha20 in Go, using the new simd and simd/archsimd packages to make the CPU do something useful.09 Hybrid PQ TLS only costs ~1 ms on fresh handshakes in this Graviton3 bench; resumption makes the overhead vanish.10 C2PA can end up signing an empty string, then you swap the pixels later via exclusion ranges. Great attack surface.11 Practical PQC migration checklist for developers, from RSA/ECC inventory to ML-KEM/ML-DSA/SLH-DSA hybrid cutover.12 YouTube talk on TikTok’s Voynich decode claim, a fresh coat of viral certainty over an old cryptanalytic corpse.13 Tool and write-up for estimating when deployed crypto falls to quantum attacks, with Shor/Grover costs and audit logs. Lovely.14 Still want to deploy Classic McEliece after BSI's advisory, or are the new key-recovery results the real warning?15 NSA Accelerates Post-Quantum Cryptography Implementation: Addressing National Security and Tech Industry Concerns dev.toNSA wants PQC sooner, so the RSA/ECC retirement plan gets pulled out of the 'someday' drawer.16 So is this really a PQC migration checklist, or the case for treating crypto agility like an ongoing ops program?17 Uses WebAuthn PRF to turn a passkey into an X25519/HPKE address, with rpId as the actual key, which is the annoying part.18 What if multihashing didn't require reading a NIST appendix? SequenceHash/MAC, with specs, vectors, and Rust/Go/Python code.19 RSA refresher for adults: keygen, factoring attacks, 896/260-bit wins, and why 2048-bit still isn’t weekend work.20 Cloudflare Workers adds opt-in Web Crypto for ML-KEM and ML-DSA behind a flag, plus JWK and HPKE hooks.21 Cloudflare plans hybrid post-quantum TLS certs with Merkle Tree Certificates, since a quantum-safe X.509 swap would be a handshake tax.22 Provable security, or just a polished way to trust assumptions you didn't verify?23 Plan ₿ Foundation announces Bitcoin Roots, a Knots-derived full node fork that stays consensus-compatible and tweaks policy.24 Assessing the Security of a Nondeterministic Encryption Method: Identifying Weaknesses and Improvements dev.toIs this homegrown nondeterministic cipher actually safe, or just frequency-attack cosplay?25 Your EIP-712 signature can change just because HexBytes.hex() changed version, which is a fun way to lose money.26 Cloudflare adds domain-level telemetry for post-quantum TLS, so you can see X25519MLKEM768 in logs now.27 Cloudflare's IKEv2 patch adds full-transcript auth, closing the active downgrade hole that strips PQ key exchange.28 Cloudflare wants to be a public CA, with ACME and a post-quantum roadmap, because the web apparently needed another root.29 Polish codebreakers got there first, and this site walks through Enigma settings, message flow, and the WWII decryption drama.30 How do you run a PQ CA without blowing up certs? Cloudflare's Merkle Tree Certificates answer that.
