cobfusc — make a C source file unreadable but compilable
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 ...]
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
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.
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.
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.
Set the output destination to file.
Specify the prefix to use when generating the identifiers.
Tell cobfusc that the identifiers contained in file must not be obfuscated.
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
Add the identifiers pairs contained in file to the obfuscation table.
