| Chapter | Topic | Actionable Task | |---------|-------|----------------| | 1 | Hashing | Implement a simple deduplication system; demonstrate length extension attack on SHA256 (use Python). | | 2 | MACs | Compare HMAC vs KMAC; write a small token verifier with timing-safe comparison. | | 3 | Symmetric Encryption | Encrypt a file with AES-GCM; deliberately corrupt the tag to see rejection. | | 4 | Asymmetric Encryption (RSA, ECIES) | Encrypt with RSA PKCS#1 v1.5 (obsolete) vs OAEP; explain padding oracle conceptually. | | 5 | Signatures | Sign a message with Ed25519; verify with public key – note nonce reuse risk. | | 6 | Key Exchange (Diffie‑Hellman) | Implement toy DH in Python; compute shared secret; add a KDF. | | 7 | Randomness & RNG | Test system RNG with ent ; discuss getrandom() vs /dev/urandom . |
