## What it is
kekeo is a C-based command-line toolbox for manipulating Microsoft Kerberos, from the author of mimikatz. It supports operations like ticket requesting, renewal, and constrained delegation abuse for security testing.

## Use cases
- request and renew kerberos tickets on windows
- test kerberos constrained delegation in active directory
- red team kerberos abuse testing
- manipulate microsoft kerberos from the command line
- security assessment of active directory authentication

## When to choose
- you need fine-grained Kerberos ticket manipulation on Windows for authorized security testing
- you are assessing Active Directory delegation attacks
- you want a lightweight C tool without heavy dependencies

## When to avoid
- you need a maintained tool with permissive licensing - the repo has no license and depends on a commercial ASN.1 library
- you want an out-of-the-box build - it requires an OSS ASN.1/C license to compile
- you need cross-platform support - it targets Windows only

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: security, cryptography, cli, developer-tools
- domain: security, penetration-testing, windows
- platform: windows, cli, cpp
- tags: kerberos, active-directory, red-team, pentesting, mimikatz-family, c
