Is there a way to check Secure Client-Initiated Renegotiation manually? All I found is only "Insecure Client-Initiated Renegotiation" using "R" command in openssl.
SSL Labs cannot be used for checking internal hosts.
When you use OpenSSL on the command line, it will report if a web site supports secure renegotiation. Try this:
$ openssl s_client -connect www.ssllabs.com:443
Then observe the output. It will say "Secure Renegotiation IS supported".
