About Certificate Key Matcher

Certificate Key Matcher is a no-nonsense utility for engineers and technical marketers. Confirm a certificate, private key and CSR all belong together. Give it your settings and it returns a metric breakdown — no sign-up, no ceremony.

Every field maps to a real property in the generated output, so you can see exactly how a setting changes the result before you ship it.

Certificate Key Matcher is included on Professional and above. Every run counts against your plan's credit allowance, and results are saved to your history so you can return to them or attach them to a client report.

How to use Certificate Key Matcher

    Enter your settings

    Fill in the fields. Each one maps to a property in the generated output.

  4. 4

Features

Every option exposed

No hidden defaults. Each field maps to a real property in the output.

Most runs complete in well under two seconds, with live progress while it works.

Export anywhere

Copy to clipboard or export to PDF, CSV, JSON or plain text in one click.

Anything that can be computed in your browser is — nothing is uploaded unless the job genuinely needs a server.

Saved to your history

Why teams use it

Stop paying for a single-purpose tool

Certificate Key Matcher is one of 312 tools on the same account. One subscription replaces the handful of point solutions most developer teams end up stacking.

Get to the decision faster

The output is structured around what you will do next, not around what was easiest to measure. Less interpretation, fewer meetings.

Share results without a screenshot

Export to PDF or CSV, or send a link. Clients and colleagues see the same thing you do, formatted properly.

Works the same on every device

The full workspace — including tables and exports — works on a phone, a tablet and a 4K display without a separate app.
