Hacking Cryptography
Cryptographic primitives rarely break. The code around them breaks constantly. Two days on how applied cryptography fails in the field — and how to find it before someone else does.

Abstract
Crypto-related bugs remain common across the software industry, and they persist for reasons that have little to do with the mathematics.
Developer misuse
Roughly 83% of cryptographic software vulnerabilities come from application developers misusing secure libraries — not from flaws in the libraries themselves.
Business logic errors
In the smart contract space, business logic errors account for a disproportionately high share of bugs.
Persistent value lost
Despite years of industry advancement, bad actors keep exploiting these code vulnerabilities successfully.
What you'll
be able to do
Find the flaw, then write the exploit
You'll leave able to find common crypto vulnerabilities in software and write crypto exploits for IoT devices and software.
Using case studies from our own pentesting and red teaming engagements, we introduce the core concepts of applied cryptography and show how each one fails in practice.

Why I offer Ruben's training
I've spent a fair amount of time decrypting ciphers and studying cryptography. I've sat in on Ruben's training twice. Both times I learned something new. He has a deep knowledge base and conveys it easily to others.

November 21–22 · AC Hotel Bellevue, WA
Two days in Bellevue, Washington with Ruben Gonzalez. Six seats — small by design — so you get real time with the trainer rather than a seat in an audience.
Cancellations can be made without a fee before August 31. After August 31, $200 is subtracted from the refund to cover non-refundable fees.
