Censys Lite Certificates
Changes Coming on September 1, 2021
In order to provide optimal search performance on high-value (i.e., unexpired) certificates in the Censys Certificates dataset, we will begin limiting searchable fields on certificates that have expired more than one year ago. We call these Censys Lite Certificates.
Lite Certificates have all the same data as regular certificates, but their ct fields and parsed.extension fields (see them here) are no longer indexed for searching in the Search API and web UI.
| Note | These fields will still be included in the certificate entity with all of their values populated, but Lite Certificates will no longer be returned for search queries that seek matches on these fields. |
This change does not impact users who download the certificates dataset or query the certificates dataset in BigQuery.
What do I need to change?
If you actively use the API or UI to query the ct fields or parsed.extension fields for certificates that have been expired for more than one year, reach out to support@censys.io and we can talk about alternative ways to access that data.
What happens if I do nothing?
You will not see a service disruption unless you query the ct or parsed.extensions fields in certificates that have been expired for more than one year.
On September 1, 2021, Lite Certificates will not be returned in any Search 1.0 or 2.0 API or UI search that specifies criteria for the two fields above.
If you do use the ct or parsed.extensions fields in searches of certificates that have been expired for more than one year, on Sept. 1, 2021 these searches will return no results.
Please see the PDF attached in our Search 1.0 and IPv4/Banners Deprecated Resources and Available Alternatives article for more detail.
