SSL Server Example

Demonstrates how to create an SSL socket for accepting connections. This example is *very* simple in that it will create an SSL socket for accepting a single connection. It will read a message from the client, send a reply, and exit.

require 'chilkat'

listenSslSocket = Chilkat::CkSocket.new()

#  Any string automatically begins a fully-functional 30-day trial.

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

#  An SSL server needs a digital certificate.  This example loads it from a PFX file.

#  Create an instance of a certificate store object, load a PFX file,
#  locate the certificate we need, and use it.
#  (a PFX file may contain more than one certificate.)
certStore = Chilkat::CkCertStore.new()
#  The 1st argument is the filename, the 2nd arg is the
#  PFX file's password:
success = certStore.LoadPfxFile("chilkat.pfx","test")
if (success != true)
    print certStore.lastErrorText() + "\n"
    exit
end

#  Find the certificate to be used for SSL:

cert = certStore.FindCertBySubject("Chilkat Software, Inc.")
if (cert == nil )
    print certStore.lastErrorText() + "\n"
    exit
end

#  Use the certificate:
success = listenSslSocket.InitSslServer(cert)
if (success != true)
    print listenSslSocket.lastErrorText() + "\n"
    exit
end

#  Bind and listen on a port:
myPort = 8123
#  Allow for a max of 5 queued connect requests.
backLog = 5
success = listenSslSocket.BindAndListen(myPort,backLog)
if (success != true)
    print listenSslSocket.lastErrorText() + "\n"
    exit
end

#  Accept a single client connection:

maxWaitMillisec = 20000
clientSock = listenSslSocket.AcceptNextConnection(maxWaitMillisec)
if (clientSock == nil )
    print listenSslSocket.lastErrorText() + "\n"
    exit
end

#  The client (in this example) is going to send a "Hello Server! -EOM-"
#  message.  Read it:

receivedMsg = clientSock.receiveUntilMatch("-EOM-")
if (receivedMsg == nil )
    print clientSock.lastErrorText() + "\n"
    exit
end

print receivedMsg + "\n"

#  Send a "Hello Client! -EOM-" message:
success = clientSock.SendString("Hello Client! -EOM-")
if (success != true)
    print clientSock.lastErrorText() + "\n"
    exit
end

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