Hacking Cryptography for Defenders - Ruben Gonzalez - DCTAC2025

Name of Training: Hacking Cryptography for DefendersTrainer(s): Ruben Gonzalez and Aaron KaiserDates: November 3-4, 2025Time: 8:00 am to 5:00 pm Venue: TBDCost: $2,200 Course Description:  Crypto related bugs are super common. OWASP even ranks "Cryptographic Failure" as the second most common security vulnerability class in software. Yet, very often these vulnerabilities are overlooked by developers, code auditors and blue teamers. Because, let's face it: Nobody knows how cryptography works. During the course you will: Understand how modern cryptography works. Find common crypto vulnerabilities in real software. Experience crypto exploits for real software and IoT devices and learn how they could have been avoided. Using case studies from our own pentesting and red teaming engagements, we'll introduce core concepts of applied cryptography and how they fail in practice. This course will teach you how applied cryptography works, how it's commonly misused in the field and how this lea
