check_certificate ~201 tokens
Connects to a domain on port 443 and reports its TLS certificate: whether it is trusted and matches the name, the issuer, the expiry date and days left, the lifetime, the chain and the TLS version, what each of its server addresses serves (up to 4 IPv4 and 4 IPv6), and, for certificates from Let’s E
check_domain_expiry ~168 tokens
