Per suggestions received for this project, I've added code to "pad" 8th bits in a
"7-bit" text file, i.e., to "normalize" the ratio of zero-bits and one-bits somewhat.
Bit-padding prior to encryption does not change the central imperative of the program,
which is to never change any bits in a file, since bit-padding is a separate option.
Attached are: CCRP.H ('C'-language header)
CCRP.C ('C'-language code)
CCRP.DOC (instructions)
CCRP.FAQ (f.a.q.)
Suggested procedure: Start with any file; if "7-bit" ASCII, try bit-padding first.
Next, perform encryption at least half a dozen times, with
different pass-phrases.
To decrypt, perform all steps in reverse, per documentation.
Comments and questions are welcome.
