ACARA 9-10 Digital Technologies: Modern cryptography and hashing
Students compare symmetric and asymmetric encryption, see how HTTPS secures data and use hashing to check integrity and store passwords.
One content description (AC9TDI10K01) from the full ACARA Digital Technologies Years 9–10 — Cyber Security Threats and Vulnerabilities journey. All 23 modules below are in that journey too, with the same content — add just these to a class, or the whole strand.
