## What it is
Certify is a C# command-line tool for enumerating and abusing misconfigurations in Active Directory Certificate Services (AD CS). It was released alongside SpecterOps' 'Certified Pre-Owned' AD CS research at Black Hat 2021.

## Use cases
- enumerate vulnerable AD CS certificate templates
- abuse Active Directory Certificate Services misconfigurations
- find escalation paths via misconfigured certificate templates
- request certificates for privilege escalation in a domain
- audit AD CS configuration for security issues
- run certificate abuse tooling in-memory via PowerShell

## When to choose
- you are performing authorized penetration testing or red team assessments against Windows Active Directory environments
- you need to enumerate or exploit AD CS template misconfigurations
- you want a C# tool that can be loaded reflectively through PowerShell or PSRemoting

## When to avoid
- you need defensive-only auditing with a formal report rather than abuse capabilities
- you cannot compile from source, since no binaries are released
- your target environment is not Windows Active Directory with AD CS deployed
