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.

LOCAL lnSuccess
LOCAL loSocket
LOCAL lnBTls
LOCAL lnMaxWaitMs

lnSuccess = 0

loSocket = CreateObject('Chilkat.Socket')

*  Connect to the server using TLS.
lnBTls = 1
lnMaxWaitMs = 5000
lnSuccess = loSocket.Connect("example.com",5000,lnBTls,lnMaxWaitMs)
IF (lnSuccess = 0) THEN
    ? loSocket.LastErrorText
    RELEASE loSocket
    CANCEL
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.
lnSuccess = loSocket.ConvertFromSsl()
IF (lnSuccess = 0) THEN
    ? loSocket.LastErrorText
    RELEASE loSocket
