How to fix curl: (60) SSL certificate: Invalid certificate chain when using sudo So since the Mavericks upgrade curl has more issues with certificates.

When trying to curl a file from my web server with it's self-signed certificate it was getting the error "SSL Certificate: Invalid certificate chain".

This was corrected by adding the certificate to my system keychain and setting it to always allow SSL, information I found here and here.

This works fine and when I curl a file it downloads properly.

However if I run curl with sudo before (e.g I have a script which needs to be run with sudo and does a curl in it) then I'm back to the same error message.

I'm guessing that root doesn't read from the system keychain perhaps?

Does anyone know a way to fix this?
f you store your CA certificates on the filesystem (in PEM format) you can tell curl to use them with

sudo curl --cacert /path/to/cacert.pem ...


You can also turn off the certificate verification with

sudo curl --insecure ...


Edit: Updated with regard to feedback

If you want to set this permanently, you should create a .curlrc files and place in your home directory. sudo commands may need this file in /var/root The file takes the same options as the command line but without the dashes. One option per line:

cacert=/path/to/my/certs.pem
