Trusting cURL with Self Signed Certs

Curl can be told to trust self signed certificates.

First, download the certificate:

openssl s_client -showcerts -servername localhost -connect localhost:443 > cacert.pem

You can press Ctrl-c if the task doesn't end.


curl -v https://localhost/hello --cacert cacert.pem

Use the --cacert command option flag.
