FCODE
▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄
FCODE is the binary file encoder/decoder of the *ONETIME* file security
package. This is the actual program that encodes and decodes binary or text
files. When encoding, it creates a file consisting of binary numbers in the
range of 0h to FFh (0 - 255 decimal). This is fine for encrypted files to be
transferred on magnetic media (diskettes, tape, removable HD's, etc.), or for
transmission by modem, but NOT suitable for printing out as hard-copy or for
faxing. Use the companion program TCODE for more general coding of text
files. Note that TCODE does not work on binary files.
FCODE will usually be invoked from the batch files FENCODE and FDECODE. It
can also function as a stand-alone utility. Type: fcode e to encode the file
named plain.txt. Type: tcode d to decode the file named encr.xxx. Using the
batch files FENCODE and FDECODE (recommended) eliminates the need to rename
the files to be encoded or decoded.
WARNING: if using FCODE as a stand-alone utility (not recommended), the files
plain.txt and code.key must already be present in the working directory.
Using the batch files provided for the purpose, FENCODE and FDECODE is much
easier.
The C source for FCODE is included for programmers wishing to use or modify
it. This requires the permission of the author, which can easily be
obtained.
