require 'chilkat'

socket = Chilkat::CkSocket.new()

success = socket.UnlockComponent("Anything for 30-day trial")
if (success != true)
    print "Failed to unlock component" + "\n"
    exit
end

#  The SSL server hostname may be an IP address, a domain name,
#  or "localhost".

sslServerHost = "www.paypal.com"
sslServerPort = 443

#  Connect to the SSL server:
success = socket.Connect(sslServerHost,sslServerPort,ssl,maxWaitMillisec)
if (success != true)
    print socket.lastErrorText() + "\n"
    exit
end

    print "Distinguished Name: " + cert.subjectDN() + "\n";
    print "Common Name: " + cert.subjectCN() + "\n";
    print "Issuer Distinguished Name: " + cert.issuerDN() + "\n";
    print "Issuer Common Name: " + cert.issuerCN() + "\n";

    bExpired = cert.IsExpired()
    bRevoked = cert.get_Revoked()
    bSignatureVerified = cert.get_SignatureVerified()

    print "Expired: " + bExpired + "\n";
    print "Revoked: " + bRevoked + "\n";
    print "Signature Verified: " + bSignatureVerified + "\n";
    print "Trusted Root: " + bTrustedRoot + "\n";

end

#  Close the connection with the server
#  Wait a max of 20 seconds (20000 millsec)
socket.Close(20000)
