S_client certificate download

S_client certificate

In order to verify a client certificate is being sent to the server, you need to analyze the output from the combination of the -state and -debug. After a while I figured it out: this particular load balancer was configured to use only TLSv, which the version of openssl included in OS X. openssl s_client [-connect host:port] [-verify depth] [-cert filename] [-key filename] [-CApath directory] [-CAfile filename] [-reconnect] [-pause] [-showcerts] [-debug].

openssl s_client [-connect host:port] [-servername name] [-verify depth] [- verify_return_error] [-cert filename] [-certform DER|PEM] [-key filename] [-keyform   SYNOPSIS - OPTIONS. The openssl tool has a command s_client which is a general SSL client; Global CA verify error:num=unable to get local issuer certificate. In that case, use the -prexit option of the openssl s_client request to ask for the openssl s_client -port -CApath /usr/share/ssl/certs/ -host.

Steps to test SSL: create a cert/key pair then use c_client Export from Firefox/IE (* *If there are key usages use Digital Signature from RFC) or. openssl s_client -connect raymondsaumure.com -servername raymondsaumure.com - showcerts So you could take certificate that you want from file. On my system (and possibly on yours), s_client doesn't pick up the default trusted certificates; it complains that there is a self-signed certificate in the certificate. openssl s_client -showcerts -ssl2 -connect raymondsaumure.com You can also present a client certificate if you are attempting to debug issues.
