DESCRIPTION¶
This document contains only a brief description ofcobfusc. 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-inumeric 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.
-cno | lower | upper | screw | 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.
-fsuffix- 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.
-gfile- Add first the identifiers contained in file to the obfuscation table. Useful when those identifiers are shared between two or more source files.
-ino | numeric | word | random- Set the identifier obfuscation mode.
-m- Strip the comments.
-n- Garble integers with expressions.
-ofile- Set the output destination to file.
-pprefix- Specify the prefix to use when generating the identifiers.
-rfile- Tell
cobfuscthat the identifiers contained in file must not be obfuscated. -sseed- 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
-gand-zparameters. -zfile- Add the identifiers pairs contained in file to the obfuscation table.
