tcl::transform::otp - Encryption via one-time pad
package require Tcl 8.6
package require tcl::transform::core ?1?
package require tcl::transform::otp ?1?
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.
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.
