Revert a TLS Connection to Plain TCP

See more Socket/SSL/TLS Examples

Demonstrates Socket.ConvertFromSsl, which ends the TLS layer while leaving the underlying TCP connection open for subsequent unencrypted communication.

llSuccess = .F.

loSocket = createobject("CkSocket")

//  Connect to the server using TLS.
llBTls = .T.
lnMaxWaitMs = 5000
llSuccess = loSocket.Connect("example.com",5000,llBTls,lnMaxWaitMs)
if (llSuccess = .F.) then
    ? loSocket.LastErrorText
    release loSocket
    return
endif

//  End the TLS layer while keeping the underlying TCP connection open for subsequent unencrypted
//  communication.  This is the reverse of a STARTTLS-style upgrade and is valid only while TLS is
//  active.
llSuccess = loSocket.ConvertFromSsl()
if (llSuccess = .F.) then
    ? loSocket.LastErrorText
    release loSocket
    return
endif
