rasc(1) Radare Shellcode helper utility

SYNOPSIS

rasc [-cCxXtLV] [-A N] [-C N] [-E N] [-N N] [-a [email protected]] [-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)
