Greetings: I uploaded otp-10.zip to your directory: OPT-PC was written by me, and I allow copies to be freely distributed. Thanks, Jim Pinson Galapagos Islands, Ecuador: 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.
