Never Decrypted: Reading the Row Without Revealing Which Row
Private information retrieval lets a server answer your query without ever learning which row you asked for -- the 1995-to-2026 mechanism and its honest cost.

How Fully Homomorphic Encryption Would Break: The Seams Above the Lattice
Fully homomorphic encryption computes on data it never decrypts. Its likeliest failure is not the post-quantum lattice beneath it, but the scheme layer above.

Never Decrypted: How Fully Homomorphic Encryption Computes on Ciphertext It Cannot Read
Fully homomorphic encryption computes on data it cannot read. Inside: the mechanism, the noise budget that governs it, bootstrapping, and the honest 2026 cost.

The Trusted Party Nobody Has to Be: Secure Multiparty Computation and Threshold Cryptography, Where No One Holds the Secret
Secure multiparty computation and threshold cryptography let distrusting parties compute on private data and sign with a key no single party ever holds.

How Elliptic Curves and Diffie-Hellman Break in Real Life: The Discrete Log Never Fell
No one has solved the discrete log on a strong curve or a 2048-bit group -- yet PS3, Android wallets, TPMs, CurveBall, and Logjam all fell. Here is exactly how.

How RSA Would Break: Why Factoring Is the Slow Path and Coppersmith Is the Fast One
Everyone says you break RSA by factoring the modulus. That is the slowest path. A structural tour of the fast lane, the slow lane, and the quantum one.

The Standard Was Boring; That Was the Point: A Field Guide to HPKE (RFC 9180)
The industry standardized encrypt-to-a-public-key four incompatible ways. HPKE (RFC 9180) is the boring, correct fix -- and its non-goals are the whole discipline.

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.
