Quick start

Install the plugin with Steampipe:

steampipe plugin install crtsh

Configure the server address in ~/.steampipe/config/crtsh.spc:

connection "crtsh" {
  plugin = "crtsh"
}

Run steampipe:

steampipe query

Query certificates:

select
  dns_names,
  not_after
from
  crtsh_certificate
where
  query = 'steampipe.io';

+------------------------+---------------------------+
| dns_names              | not_after                 |
+------------------------+---------------------------+
| ["steampipe.io"]       | 2022-10-24T08:48:52-04:00 |
| ["cloud.steampipe.io"] | 2022-10-20T22:56:08-04:00 |
+------------------------+---------------------------+

Enumerate and discover subdomains for a given domain:

with raw_domains as (
  -- Search for any certificates matching steampipe.io
  select distinct
    jsonb_array_elements_text(dns_names) as domain
  from
    crtsh_certificate
  where
    query = 'steampipe.io'
)
select
  *
from
  raw_domains
where
  -- filter out mixed domains (e.g. from shared status page services)
  domain like '%steampipe.io'
order by
  domain;

+--------------------+
| domain             |
+--------------------+
| cloud.steampipe.io |
| hub.steampipe.io   |
| steampipe.io       |
| www.steampipe.io   |

Engines

This plugin is available for the following engines:

Engine	Description
Steampipe	The Steampipe CLI exposes APIs and services as a high-performance relational database, giving you the ability to write SQL-based queries to explore dynamic data. Mods extend Steampipe's capabilities with dashboards, reports, and controls built with simple HCL. The Steampipe CLI is a turnkey solution that includes its own Postgres database, plugin management, and mod support.
Postgres FDW	Steampipe Postgres FDWs are native Postgres Foreign Data Wrappers that translate APIs to foreign tables. Unlike Steampipe CLI, which ships with its own Postgres server instance, the Steampipe Postgres FDWs can be installed in any supported Postgres database version.
SQLite Extension	Steampipe SQLite Extensions provide SQLite virtual tables that translate your queries into API calls, transparently fetching information from your API or service as you request it.
Export	Steampipe Plugin Exporters provide a flexible mechanism for exporting information from cloud services and APIs. Each exporter is a stand-alone binary that allows you to extract data using Steampipe plugins without a database.
Turbot Pipes	Turbot Pipes is the only intelligence, automation & security platform built specifically for DevOps. Pipes provide hosted Steampipe database instances, shared dashboards, snapshots, and more.
