## What it is
SharPyShell is a Python tool that generates a tiny, obfuscated ASP.NET webshell for C# web applications on .NET Framework and provides an interactive encrypted-channel terminal for post-exploitation. It compiles C# and PowerShell code in memory at runtime to evade file and network signature detection.

## Use cases
- generate an obfuscated aspx webshell for a pentest engagement
- interact with a compromised IIS server through an encrypted channel
- run post-exploitation commands on a restricted web server with limited network access
- perform privilege escalation and lateral movement from a webshell
- evade IDS signatures during authorized penetration testing

## When to choose
- you are a penetration tester needing stealthy post-exploitation on an ASP.NET/IIS target
- the compromised server has heavily restricted inbound and outbound connections
- you need in-memory C# or PowerShell execution without dropping detectable payloads

## When to avoid
- you need a full-featured C2 framework like Meterpreter or Empire
- your target runs VB.NET instead of C#
- you are not operating in an authorized security testing context

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: penetration-testing, security, cryptography, cli
- domain: penetration-testing, security, web-development
- platform: python, cli, windows
