tcl::transform::otp - Encryption via one-time pad

::tcl::transform::otpchankeychanwkeychanr
              This command creates a one-time pad based encryption transformation on top of the channel chan and
              returns its handle.

              The  two  channels  keychanw  and  keychanr  contain  the  one-time  pads  for  the write and read
              directions, respectively. Their contents are reads and xored with the bytes written  to  and  read
              from the channel.

       This  document,  and  the package it describes, will undoubtedly contain bugs and other problems.  Please
       report such in the category virtchannel of the  TcllibTrackers  [http://core.tcl.tk/tcllib/reportlist].
       Please also report any ideas for enhancements you may have for either package and/or documentation.

       When proposing code changes, please provide unifieddiffs, i.e the output of diff-u.

       The  tcl::transform::otp  package  provides  a  command  creating  a  channel  transformation  which uses
       externally provided one-time pads to perform encryption (on writing) and decryption (on reading).

       A related transformations in this module is tcl::transform::rot.

       The internal TclOO class implementing the transform handler is a sub-class  of  the  tcl::transform::core
       framework.
