Examples

Log entries for a particular certificate

Determine the log entries associated with a specific certificate to analyze its activity and troubleshoot potential issues.

select
  *
from
  crtsh_log_entry
where
  certificate_id = 6760944046;

select
  *
from
  crtsh_log_entry
where
  certificate_id = 6760944046;

Most recent entries for a given log

Analyze the most recent entries in a given log to monitor changes or unusual activity over the past hour. This can be particularly useful for identifying potential security issues or troubleshooting ongoing problems.

select
  *
from
  crtsh_log_entry
where
  certificate_id = 6760944046
  and ct_log_id = 91
  and entry_timestamp > now() - interval '1 hr';

select
  *
from
  crtsh_log_entry
where
  certificate_id = 6760944046
  and ct_log_id = 91
  and entry_timestamp > datetime('now', '-1 hour');

Export

This table is available as a standalone Exporter CLI. Steampipe exporters are stand-alone binaries that allow you to extract data using Steampipe plugins without a database.

You can download the tarball for your platform from the Releases page, but it is simplest to install them with the steampipe_export_installer.sh script:

/bin/sh -c "$(curl -fsSL https://steampipe.io/install/export.sh)" -- crtsh

You can pass the configuration to the command with the --config argument:

steampipe_export_crtsh --config '<your_config>' crtsh_log_entry
