DESCRIPTION

22       The  tcl::transform::otp  package provides a command creating a channel
23       transformation which uses externally provided one-time pads to  perform
24       encryption (on writing) and decryption (on reading).
25
26       A related transformations in this module is tcl::transform::rot.
27
28       The  internal  TclOO class implementing the transform handler is a sub-
29       class of the tcl::transform::core framework.

API

32       ::tcl::transform::otp chan keychanw keychanr
33              This command creates a one-time pad based encryption transforma‐
34              tion on top of the channel chan and returns its handle.
35
36              The two channels keychanw and keychanr contain the one-time pads
37              for the write and read directions, respectively. Their  contents
38              are  reads and xored with the bytes written to and read from the
39              channel.
