Q-Day Has Not Happened. The Incident Already Has: Harvest Now, Decrypt Later
No quantum computer can break RSA in 2026, yet long-lived secrets encrypted today may already be lost. Harvest now, decrypt later is a deployment failure.

How AES Breaks in Real Life: The Attacks That Never Touched the Cipher
AES-the-cipher has never been broken in the field -- its deployments have. KRACK, repeated GCM nonces, and cache timing broke the wrapper, never the block.

How RSA Breaks in Real Life: ROCA, Bleichenbacher's Ghosts, FREAK, and the Keys That Shared a Prime
No one has ever factored a strong, deployed RSA key -- yet ROCA, Bleichenbacher's oracle, DROWN, and FREAK broke real RSA anyway. The break was never the factoring.

They Read Your Plaintext Without Breaking Your Cipher: A Field Guide to Padding Oracles
A padding oracle reads your plaintext without touching your key. Why CBC, Vaudenay, Lucky13, and POODLE are one bug -- and why Encrypt-then-MAC ends it.

A Perfect Signature for a Certificate That Should Never Have Existed: A Field Guide to X.509 and PKI
How the Web PKI turns a certificate into a trust decision -- path validation, revocation, and Certificate Transparency -- and every famous way that trust broke.

Rotating Every Cipher: SChannel and the Twenty-Year Algorithm-Agility Story of Windows TLS
How one Windows DLL rotated every TLS primitive from RC4 to ML-KEM without breaking IIS, RDP, SQL Server, or .NET SslStream -- and why Vista's 2007 CNG was the inflection point.

Post-Quantum Cryptography on Windows: The Thirty-Year Migration That Just Arrived
How NIST FIPS 203/204/205 reaches the Windows platform via SymCrypt, CNG, Schannel, and .NET 10 -- the algorithm internals, the wire format, the migration timeline, and the honest accounting.
