🔐Applied Modern Cryptography

Build the cryptographic judgment to evaluate any system's security posture. You will be able to choose the right primitive for each job (AES-GCM, HMAC, Argon2, ECDH, Ed25519), explain why common constructions fail (ECB, textbook RSA, nonce reuse, bare CTR), read a TLS 1.3 handshake trace, and audit real code for the most dangerous cryptographic misuses.
