What is Sentrint Tools?
Sentrint's free tools page: six front-end security tools that all run locally in the browser — a JWT debugger (catches alg:none, missing expiry), a secret scanner (finds leaked keys in diffs), a CSP evaluator, an SRI hash generator, hash calculation and Base64 encoding, plus a JSON formatter/validator/diff tool. No account needed, nothing uploaded — just open and use.

How to use Sentrint Tools
- Paste a JWT into the debugger when checking auth tokens — common misconfigs stand out.
- Score your content security policy with the CSP evaluator before launch and tighten per its advice.
- Generate integrity attributes for CDN scripts with the SRI tool and paste them in.
- Drop a suspicious .env or diff into the secret scanner to check for leaks.
