Curl: disable certificate verification

Question

I am developing and I need to access https://localhost. I know the certificate will not match. I just want curl to ignore that. Currently it gives me the following error message:

curl: (51) SSL peer certificate or SSH remote key was not OK

Is it possible to tell curl to perform the access anyway?

Brad Parks · Answer

If you truly want to disable curl SSL verification, by default, for ALL use cases, you can do as suggested in this Unix stack exchange answer:
$ echo insecure >> ~/.curlrc

Now should you do this? No, as this is avoiding security checks you should have in place... but if you really really want to do this, caveat emptor!

curl -k  or curl --insecure does NOT fix this particular error condition:
curl: (51) SSL peer certificate

Mathias R. Jessen · Answer

Yeah, you can do that. From curl --help or man curl:

-k, --insecure
  
  (SSL) This option explicitly allows curl to perform "insecure" SSL
  connections and transfers. All SSL connections are attempted to be
  made secure by using the CA certificate bundle installed by default.
  This makes all connections considered "insecure" fail unless -k,
  --insecure is used.
