Three tracks, one certificate
Every track is written to be read in one sitting. The exam draws from all three, so the certificate means you covered the whole path from key material to a running certificate authority.
SSL/TLS and HTTPS operations
Understand what TLS protects, how the handshake validates the server, how cipher suites and forward secrecy work, and how to keep HTTPS healthy in production.

- 01
Enter your full name
The name is used to render the certificate and is never stored on our side.
- 02
Answer 40 questions in one sitting
Questions are drawn at random from a pool of 100 covering PKI, SSL/TLS and ADCS. Grading happens on the server, so the answer key never reaches the browser.
- 03
Score 34 or better to pass
That is 85%. If you pass, the certificate is generated immediately with a signed link anyone can verify.
