- Use per-password random salt with PBKDF2-HMAC-SHA256 (stored as salt:hash) - Increase PBKDF2 iterations to 600,000 (OWASP 2023 recommendation) - Password for downloads now accepted via POST body (never URL query param) - Fail download request if view count cannot be incremented (prevents bypass) - Update tests to match new hashing format and POST password download Co-authored-by: christianlouis <361235+christianlouis@users.noreply.github.com>
