_________________________________________________________________________________________________

DESCRIPTION

       This   package   provides   the  XGoogleToken  authentication  mechanism  for  the  Simple
       Authentication and Security Layer (SASL).

       Please read the documentation for package sasl for details.

TLS SECURITY CONSIDERATIONS

       This package uses the TLS package to handle the security for https urls and  other  socket
       connections.

       Policy  decisions like the set of protocols to support and what ciphers to use are not the
       responsibility of TLS, nor of  this  package  itself  however.   Such  decisions  are  the
       responsibility of whichever application is using the package, and are likely influenced by
       the set of servers the application will talk to as well.

       For      example,      in      light      of      the      recent      POODLE       attack
       [http://googleonlinesecurity.blogspot.co.uk/2014/10/this-poodle-bites-exploiting-
       ssl-30.html] discovered by  Google  many  servers  will  disable  support  for  the  SSLv3
       protocol.   To handle this change the applications using TLS must be patched, and not this
       package, nor TLS itself.  Such a patch may be  as  simple  as  generally  activating  tls1
       support, as shown in the example below.

                  package require tls
                  tls::init -tls1 1 ;# forcibly activate support for the TLS1 protocol

                  ... your own application code ...
