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.
