How Q-Day Breaks Everything: Shor's Algorithm and the Simultaneous Fall of RSA, Diffie-Hellman, and ECC
RSA, Diffie-Hellman, DSA, and elliptic curves share one abelian period. A single quantum computer running Shor's algorithm reads it and breaks all four at once.

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.

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.

RSA Is a Trapdoor, Not a Cryptosystem: OAEP, PSS, and the 25-Year Padding-Oracle Lineage
Textbook RSA is a trapdoor, not a cryptosystem. A field guide to OAEP, PSS, PKCS#1 v1.5, and the Bleichenbacher-ROBOT-Marvin padding-oracle lineage, done right.
