02 / Problem and response
Make certificate triage fast and operator-readable.
Constraint
Certificate issues are often checked across several tools when operators usually need one fast view of health and risk.
Approach
justifycert bundles certificate inspection, weak algorithm checks, SAN visibility, and validation signals into one workflow.
03 / Architecture and boundaries
One focused inspection presents separate trust, identity, and expiry checks.
TLS inspection routines designed around readable output.
Focused checks for chain validity, naming, and certificate health.
Validation Surface
The command focuses on high-signal certificate checks instead of broad configuration sprawl.
Operator Output
Readable terminal output is prioritized so issues can be triaged quickly.
- 01
The value of the tool comes from reducing certificate triage time, not from exposing every possible TLS detail.
04 / Package surface
A small interface, in use.
Install
pip install justifycertUsage
justifycert example.com --check-expiry --check-san --check-chain05 / Current state and next work
What exists, and what follows.
Published
The maintained PyPI package focuses on the certificate checks shown in its documented command interface.

Next direction
- Add broader reporting formats and more environment-specific validation helpers.
Security tooling gets adopted faster when the output is immediately actionable.
