Crypto Hero

Protect data with strong cryptography (AES, RSA, SHA) and attack these systems (Existential Forgery, Padding Oracle, and more).  Make Ethereum smart contracts in Solidity and hack them, and configure private Multichain blockchains.

This is a hands-on workshop with a series of CTF-style challenges, beginning with simple data conversions and extending to advanced methods appropriate for experts.  We will briefly explain and demonstrate the techniques, and will help participants individually with the challenges.

Most challenges require nothing more than a computer with the Chrome web browser.  No prior programming or cryptography experience is necessary.
