A polyglot payload generator

**Introduction**  
SNOWCRASH creates a script that can be launched on both Linux and Windows machines. Payload selected by the user (in this case combined Bash and Powershell code) is embedded into a single polyglot template, which is platform-agnostic.  
There are few payloads available, including command execution, reverse shell establishment, binary execution and some more :\>

**Basic usage**

1. Install dependencies: `./install.sh`
2. List available payloads: `./snowcrash --list`
3. Generate chosen payload: `./snowcrash --payload memexec --out polyglot_script`
4. Change extension of the polyglot script: `mv polyglot_script polyglot_script.ps1`
5. Execute polyglot script on the target machine

**Additional notes**  
Delay before script run and payload execution can be specified as an interval (using `--sleep` flag) in the form:

```auto
x[s|m|h]

```

where

```auto
x = Amount of interval to spend in idle states = Secondsm = Sinutesh = Hours

```

After generation, the extension of generated script containing the payload can be set either to `.sh` or `.ps1` (depending on the platform we want to target).  
Generated payload can be written directly to STDOUT (instead of writing to a file) using `--stdout` flag.
