SSL Certificate Validation

When establishing a secure connection to a cloud provider endpoint, Libcloud verifies server SSL certificate. By default, Libcloud searches paths listed in for CA certificate files.

CA_CERTS_PATH contains common paths to CA bundle installations on the following platforms:

  • openssl on CentOS / Fedora
  • ca-certificates on Debian / Ubuntu / Arch / Gentoo
  • ca_root_nss on FreeBSD
  • curl-ca-bundle on Mac OS X

If no valid CA certificate files are found, you will see an error message similar to the one bellow:

No CA Certificates were found in CA_CERTS_PATH.
