Introduction

Revssl was created mainly to automate the OpenSSL reverse shell idea @int0x33/day-43-reverse-shell-with-openssl-1ee2574aa998">from here, and pack it into a single
script. It can generate agents both for Linux and Windows, providing a secure and encrypted remote control channel. I am still working on OSX implementation.
This code isn’t perfect, so feel free to open new issues and contribute :D
