ShellGen (Shell Generator) This is a simple script that will generate a specific or all shellcodes for CTFs using the VPN IP address on tun0 (the IPv4). INFORMATION Update has been made from sys library to argparse library (done in version 0.8) [hide][Hidden Content]]

Dynamic and extensible shell code generator with multiple output types which can be formatted in binary, hexadecimal, and the typical shellcode output standard. ShellGen is a dynamic shell code generator with multiple output types which can be formatted in binary, hexadecimal, and the typical shellcode output standard. Outputs are also able to be encrypted and shellcode can be generated by either reading all of the bytes of a particular file or a byte array, whether that's embedded, or again, read in from a filestream. The generated output is structured in what is called a Shell and contains a few properties: ID // The alphanumeric value assigned to the generated shell for easy maintainability. Code // The actual plainbyte/encrypted byte code of a specified file or raw bytes. Error // Any caught exception if anything goes wrong during generation. A Shell also has a serializable property allowing the ability to serialize the entire structure to a file or byte array instead of copying individual components of the generated shell object.
