SSL Certificate check

Performs network SSL Certificate validation. SSL certificate is checked from host/port (which makes possible to check not only HTTPS services, but IMAPS, POP3S and anything else).

Alert if certificate is not valid (e.g. self-signed) or if it’s already expired or will expire in less then days.

If addr specified in options, certificate will by downloaded from this address. This is sometimes needed if you have more then one server with same DNS name, and want to check each of them.

If noverify (or ssl_noverify) specified in options, SSL verification will be skipped. This makes possible to check self-signed certificates.
