Non-Geek Tools
We got you.
Useful things that run right here in your browser. No install, no account, no data leaving your machine.
Built for the person who got handed a .cer file and a deadline. Zero jargon, all answers.
Certificate Inspector
Paste a PEM certificate (the -----BEGIN CERTIFICATE----- block) and get a plain-language breakdown. Expiry date, subject, issuer — the things you actually need to know.
Everything runs in your browser. Your certificate never leaves your device.
Domain Certificate Lookup
Enter a domain name and see what certificates have been publicly logged for it — expiry dates, issuing CA, and common names. Useful for checking your own certs or investigating a domain.
Data comes from crt.sh, the public certificate transparency log search engine. Results reflect publicly issued TLS certificates only — internal / private CA certificates don't appear here.
Password & PFX PIN Generator
Generate secure passwords for PFX exports, certificate store backups, service accounts — whatever needs a strong random string. Uses your browser's cryptographic random number generator, not some math.random() nonsense.
PEM ↔ Base64 Converter
Strip or add the -----BEGIN/END----- headers. Sometimes you need just the raw Base64, sometimes you need the full PEM. Here you go.
