> Verification of SSL/TLS certificates is off by default 
> (http.tls.certificates.check = false).
> If verification is off, a no-op X509TrustManager is used in the protocol 
> implementations to bypass the verification.
> For a web crawler, it can be a valid use case to skip the certificate 
> verification, in order to crawl sites with expired or self-signed 
> certificates. But this shouldn't be the default.
