NAME

     ragg2-cc -- CC frontend for compiling shellcodes

SYNOPSIS

     ragg2-cc [-a arch] [-b bits] [-k kernel] [-o file] [-dscxvh]

DESCRIPTION

     ragg2-cc is a frontend of CC. It is used to creates tiny binaries (1KB) or shellcodes in binary or hexpairs from a C source.

     The compiler used is the one configured by the CC environment. This has been tested with gcc, llvm-gcc and clang.

     Uses sflib (shellforge4) includes to get the syscall definitions.

     Only linux/darwin x86-32/64 is supported at the moment. Planned support for more architectures.

OPTIONS

     -a arch	 set architecture x86, arm

     -b bits	 32 or 64

     -k kernel	 windows, linux or osx

     -o file	 output file to write result of compilation

     -h 	 show help message

     -v 	 show version

     -d 	 show assembler code

     -s 	 generate assembly file

     -c 	 generate compiled shellcode

     -x 	 show hexpair bytes

EXAMPLE

       $ cat hi.c
       int main() {
	 write (1, "Hello World
", 12);
	 exit (0);
       }

       $ ragg2-cc hi.c
       hi.c.bin

       # Linked into a tiny binary. This is 294 bytes
       $ wc -c < hi.c.bin
	  294

       $ ./hi.c.bin
       Hello World

       # The compiled shellcode has zeroes
       $ ragg2-cc -x hi.c

       $ ragg2 -e xor -c key=32 -B `ragg2-cc -x hi.c`
