ASN.1 Editor

Note: PKI Solutions is no longer actively supporting or maintaining the ASN.1 Editor. Its core purpose—making PKI data more accessible and understandable—continues in PKI Spotlight®, which offers deeper, real-time insight into certificate structures, revocation data, and PKI health across your environment.

The Future Is PKI Spotlight

Developed initially as a free utility to help engineers, developers, and security professionals inspect and decode ASN.1 data structures commonly used in certificates, CRLs, and PKI-related protocols, it was a lightweight tool for analyzing binary and Base64-encoded ASN.1 data. While the standalone ASN.1 Editor is no longer supported, its spirit lives on in PKI Spotlight — our modern, real-time platform for monitoring, visibility, and security posture management across your entire PKI environment.

PKI Spotlight gives you operational and security insight into the same ASN.1-based data structures used in:

  • Certificates and Certificate Chains

  • Certificate Revocation Lists (CRLs)

  • Authority Information Access (AIA) and CRL Distribution Points (CDP)

  • OCSP Responses

  • Certificate Templates and Policies

With PKI Spotlight, you’re no longer limited to manual inspection of individual certificate files. Instead, you gain always-on visibility, real-time alerts, and proactive detection of misconfigurations and security risks — including those encoded in ASN.1.

Need Help Understanding Your PKI Data?

Our legacy tools were built to solve a gap in visibility. PKI Spotlight fills that gap — and goes far beyond. If you’re looking for ASN.1 inspection as part of broader PKI validation, monitoring, and compliance, request a demo or contact us to see how we can help.

  • Real-time certificate chain validation and decoding

  • OCSP and CRL location verification and reachability

  • Detection of invalid or expired AIA/CDP values

  • Inspection of certificate templates, policies, and cryptographic algorithms

  • Monitoring of PKI and HSM health across multi-vendor environments

PKI Spotlight is not just a tool — it’s a platform designed to uncover what you can’t see with legacy utilities.
