DESCRIPTION¶
This document contains only a brief description of
cobfusc.
For a more complete documentation, please read the Info file or the Texinfo
manual.
The
cobfusc utility converts the input file, written in the C
language, into a human unreadable one, but compilable. The main work is
converting every identifier into a meaningless one, removing any comment and
compacting all the white-spaces when they are not required.
The options are as follows:
- -A
- Enable a heavy obfuscation for the source file. This is
equivalent to the -ademt -i
numeric options. The digraphize option is not
enabled by default since the Amendement 1 (1994) changes to
ANSI X3.159-1989 (“ANSI C89”) are
supported only by few C compilers.
- -a
- Garble every string with octal escapes.
- -b
- Enable the digraphize mode.
- -c
no \*(Ba lower \*(Ba upper \*(Ba screw \*(Ba
random
- Set the identifier case obfuscation mode.
- -d
- Compact the macros removing backslashes and white-spaces
when they are not required.
- -e
- Compact the white-spaces when they are not required.
- -f
suffix
- Put the output of each processed file in a separate file
with suffix appended to file name instead of
standard output. This is useful when processing a package with a lot of
source files.
- -g
file
- Add first the identifiers contained in
file to the obfuscation table. Useful when those
identifiers are shared between two or more source files.
- -i
no \*(Ba numeric \*(Ba word \*(Ba random
- Set the identifier obfuscation mode.
- -m
- Strip the comments.
- -n
- Garble integers with expressions.
- -o
file
- Set the output destination to
file.
- -p
prefix
- Specify the prefix to use when generating the
identifiers.
- -r
file
- Tell cobfusc that the identifiers
contained in file must not be obfuscated.
- -s
seed
- Specify the seed for generating the random numbers.
- -t
- Enable the trigraphize mode.
- -u
- Dump the symbol table to file.
- -V
- Print version information on standard output then
exit.
- -w
- Set the width limit of the output.
- -x
- Exclusive mode; obfuscate only the identifiers specified by
the -g and -z parameters.
- -z
file
- Add the identifiers pairs contained in
file to the obfuscation table.
