Awarded for completing Digital Signatures, Key Management and Public Key Infrastructure and passing its exam, demonstrating the ability to evaluate signature schemes, certificate chains, revocation, key custody and code signing practices in a real system.
Certificates are designed to be checked, not just displayed.
The credential is valid for 12 months from issue. Its public page states the expiry date, and renewing means passing the current exam again — so the credential always reflects the current material.
