## What it is
ACMESharp is an ACME protocol client library and PowerShell module for the .NET platform, primarily used to obtain and manage certificates from Let's Encrypt. It includes provider extensions for challenge handling and certificate installation on targets like IIS, Windows, AWS, and CloudFlare.

## Use cases
- request Let's Encrypt certificates from PowerShell
- automate TLS certificate renewal on Windows servers
- install certificates into IIS or the Windows cert store
- answer ACME challenges via AWS Route 53 or CloudFlare DNS
- embed ACME certificate issuance in a .NET application

## When to choose
- you need ACME/Let's Encrypt support in .NET or PowerShell
- you automate certificate management on Windows/IIS or AWS
- you want a scriptable alternative to the official Let's Encrypt client

## When to avoid
- you need ACME v2 or .NET Standard support - use ACMESharp Core instead
- you want a general-purpose TLS tool outside certificate issuance
- you need a actively developed project with modern .NET support

## Facets
- artifact type: library
- maturity: maintenance
- function: security, cryptography, cli, sdk
- domain: security, developer-tools, web-development
- platform: windows, dotnet, cross-platform
- tags: acme-protocol, letsencrypt, tls-certificates, powershell-module, certificate-management, automation
