TCODE
▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄
TCODE is the actual program in the *ONE TIME* file security package that
encodes and decodes text files. When encoding, it creates a file consisting
of 5-letter groups of encrypted text suitable for printing out as hard-copy
or for faxing. [The use of 5-letter groups is traditional in cryptography.]
Use the companion program FCODE for more general coding of binary or text
files. Note that FCODE does not produce output suitable for printing as
hard-copy.
TCODE will usually be invoked from the batch files TENCODE and TDECODE. It
can also function as a stand-alone utility. Type: tcode e to encode the file
named plain.txt. Type: tcode d to decode the file named encr.xxx. Using the
batch files TENCODE and TDECODE (recommended) eliminates the need to rename
the files to be encoded or decoded.
WARNING: if TCODE is used as a stand-alone utility (not recommended), the
files plain.txt and code.key must already be present in the working
directory. It is *much* easier to invoke TCODE from the batch files provided
for the purpose, TENCODE (to encode) and TDECODE (to decode).
The C source for TCODE is included for programmers wishing to use or modify
it. This requires the permission of the author, which can easily be
obtained.
