SSL checker. Is the padlock right?

Type a domain. We connect to it on port 443 as a browser would and tell you, in plain words, whether its certificate can be trusted.

  • Renew before the end

    Most certificates last 90 days or less now. On Tanzahost, they renew by themselves, 30 days before the end.

  • Send the whole chain

    A server must send its certificate and the ones in between. Phones are stricter than laptops about it.

  • Cover every name

    duka.co.tz and www.duka.co.tz are two names. The certificate must list each one your visitors use.
