Verificador de certificado SSL
Análisis detallado del certificado SSL/TLS: validez, cadena, SAN, clave, firma.
Datos clave
Check an SSL certificate online: enter a domain and see at once when it expires, who issued it, which domains it covers and whether a browser would trust it. Free, no sign-up. The tool does not test TLS versions, ciphers or revocation.
- Precio
- Gratis
- Registro
- No necesario
- Procesamiento
- On our server: it connects to your site over HTTPS (with SNI), first validates the chain like a browser, and on failure still reads the certificate so it can explain the problem
- Entrada
- A domain or site address (for example example.com); a port can be given in the address, 443 by default
- Límites
- 30 checks per minute per IP, no sign-up and no daily limit; public addresses only
- Resultado
- Expiry date and days left, issuer, domains in the SAN, key type and size, signature algorithm, the certificate chain and a list of problems (expired, wrong name, self-signed, chain cannot be built)

Verificador de certificado SSL
Check a website's SSL certificate the way a browser validates it: expiry date and days left, the domains it covers (SAN), issuer, key type and size, signature algorithm and the chain the server sends. If the certificate has expired, was issued for another name or the server omits the intermediate certificate, the check returns a connection error.
Cómo usar
- Enter a domain or page URL; add a port after a colon if needed
- Check the expiry date and the domains in the SAN
- If you get an error instead of a report, find the cause in the table below

Desplaza la tabla hacia los lados
Dónde somos más débiles: we do not test TLS versions, ciphers, vulnerabilities, revocation or HSTS, and there is no letter grade or expiry reminders.
Cuándo elegir PromoPilot: When you need to quickly see why a browser complains about a certificate or when it expires. If you need an assessment of server settings (TLS versions, ciphers, vulnerabilities), use a full configuration scanner.
