OPT-PC was written by me, and I allow copies to be freely distributed.

Description:
-----------------------------------------------------------------------
This is the first public release of OTP-PC, which is a MS-DOS
implementation of the one-time pad or Vernam Cipher. The one-time pad
is the only encryption method proven to be unbreakable.
Complete source code, of course!
OTP-PC features:
-Automatic compression of plain text messages prior to encryption.
Compression reduces consumption of the pad, and masks the size of the
original document. (compression can be overridden)
-Automatic wiping of the pad (codebook), to prevent reuse on both
encryption and decryption.
-Wiping and deletion of intermediate compressed files.
-Two stage cipher text headers. The first stage header is un-encrypted,
and contains information needed to start decryption. The second stage
contains sensitive information, and is encrypted.
-A 32 bit CRC stored in the encrypted header verifies reconstruction of
the original file.
-A verbose mode which displays encryption/decryption statistics.
