Add self signed certificate to ubuntu for use with curl

Question

I'm developing a program where I have a virtual development server that runs with a self signed certificate. My program uses curl to connect to the server and pull information, but needs to do so with SSL. When I try to connect I get the error "SSL certificate problem, verify that the CA cert is OK." When running firefox I can add the certificate to just firefox, but that doesn't help me with curl. How do I add the certificate for curl to recognize?

curl 7.19.7 (x86_64-pc-linux-gnu) libcurl/7.19.7 OpenSSL/0.9.8k zlib/1.2.3.3 libidn/1.15 Protocols: tftp ftp telnet dict ldap ldaps http file https ftps Features: GSS-Negotiate IDN IPv6 Largefile NTLM SSL libz

Ubuntu 10.04 Lucid Lynx 64bit

Answer 1

This is one way that worked for me:

First, get the CA cert from the development domain and save it to a file called 'logfile'. (Assumes port 443 for SSL)

openssl s_client -connect xxxxx.com:443 |tee logfile

Then, use the --cacert curl option to use the saved certificate file.

curl --cacert logfile **THE REST OF YOUR CURL COMMAND**
