-This directory contains client and server examples for the "Server Name
-Indication" (SNI) feature.
-
-Run server.py with no arguments.  It will accept one client connection and
-then exit.  It has two certificates it can use, one for "example.invalid"
-and another for "another.invalid".  If a client indicates one of these names
-to it, it will use the corresponding certificate for that connection (if a
-client doesn't indicate a name or indicates another name, it won't try to
-use any certificate).
-
-Run client.py with one argument, the server name to indicate.  For example:
-
-  $ python client.py example.invalid
-  Connecting... connected ('127.0.0.1', 8443)
-  Server subject is <X509Name object '/OU=Security/O=pyOpenSSL/CN=example.invalid/ST=New York/C=US/emailAddress=invalid@example.invalid/L=New York'>
-  $
-
-Depending on what hostname is supplied, the server will select a different
-certificate to use and the client output will be different.
