I've searched the web but with no luck ;) try the ones in the NSSCipherSuite section of https://git.fedorahosted.org/cgit/mod_nss.git/plain/docs/mod_nss.html There seems to be differences between CentOS 6 and CentOS 5. Your working curl cmdline does not work for me on C5, but it works on C6... Then, curl has a '--engine list' option. On C5, I get padlock and dynamic. On C6, I get nothing... JD
