Not professional advice

Content about security (JWTs, CSP, CORS, permissions) and infrastructure (subnetting, redirects, cron) is educational, not professional security or systems consulting. Production decisions should be validated against your own environment and, where stakes are high, reviewed by qualified professionals.

Tool-specific notes

• JWT tools decode tokens but do not verify signatures. Never make authorization decisions based on decoded claims alone.
• Generated configurations (.htaccess, CORS, CSP) are syntactically correct starting points; test them on a staging environment before production.
• Network calculators are IPv4-only and compute standard subnet math; exotic routing setups may differ.
• Cron calculations use your browser's timezone; servers frequently run in UTC.
