NAME

       rasc — Radare Shellcode helper utility

SYNOPSIS

       rasc [-cCxXtLV] [-A N] [-C N] [-E N] [-N N] [-a addr@off] [-s hexpair] [-i name] [-S file] [-l port]

DESCRIPTION

       rasc  implements  the most common practices to generate shellcodes with paddings with 0x41's ('A'), nops,
       breakpoints or enumerations (00 01 02 03 ..).

       rasc can serve a syscall proxy at a specified port with -l [port]

       There's an hardcoded database of common used shellcodes that can be listed with -L.  Use  -i  to  specify
       which want you want to use.

       The output can be raw or in hexpairs (-x) or C array (-c).

       Use -X to inline execute the specified. (useful for testing)

       To specify the

       -A|-C|-E|-N count
                   Specify  the  number  of  'A's,  breakpoints,  enumerations  and  nops  to be prefixed to the
                   shellcode.

       -a addr@off
                   Set the return address at a specified offset inside the resulting shellcode

       -s 'hexpair'
                   Set the shellcode in hexpair format. For example (-s '01 02 03')

       -l port     Listen a syscall proxy server at a specified port.

       -L          List all hardcoded shellcodes

       -c          Show output in C array format

       -x          Show output in hexpairs format

       -X          Execute resulting shellcode

       -t          Performs some tests on the current platform

       -h          Show usage help message.

ENVIRONMENT

       Some shellcodes can be modified using the environment variables CMD, HOST  and  PORT.  See  -L  for  more
       information.
