NAME

       cobfusc — make a C source file unreadable but compilable

SYNOPSIS

       cobfusc [-AabdemntxV] [-c case] [-f suffix] [-g file] [-i idobf]
               [-o file] [-p prefix] [-r file] [-s seed] [-u file] [-w cols]
               [-z file] [file ...]

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 | 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.

       -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 | numeric | word | 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.
