Passive SSL
|
||
|
|
-----------
|
||
|
|
|
||
|
|
Passive SSL is a database storing historical X.509 certificates seen per IP address. The Passive SSL historical data is indexed per IP address, which makes it searchable for incident handlers, security analysts or researchers.
|
||
|
|
|
||
|
|
## How can you collect SSL certificates?
|
||
|
|
|
||
|
|
The Passive SSL database can public scanning datasets like the excellent [scans.io project](http://scans.io/).
|
||
|
|
|
||
|
|
For more information, [Passive SSL was presented at FIRST 2015 in Berlin](https://www.first.org/resources/papers/conf2015/first_2015_-_leverett_-_dulaunoy_-_passive_detection_20150604.pdf).
|
||
|
|
|
||
|
|
## How to start the API service?
|
||
|
|
|
||
|
|
You have to run [ip-ssl-subject-api.py](https://github.com/adulau/crl-monitor/blob/master/bin/x509/ip-ssl-subject-api.py) on the server where the import was done in the redis server.
|
||
|
|
|
||
|
|
## How to use the service?
|
||
|
|
|
||
|
|
Passive SSL is accessible via a REST API and the output is in JSON format.
|
||
|
|
|
||
|
|
The REST API is accessible via the following URLs. 'query' is to query IP address or CIDR blocks (/32 up to /23). 'cquery' is to query per certificate fingerprint and find where the certificate is used per IP address. 'cfetch' is to fetch and parse a specified certificate from the Passive SSL store by its fingerprint.
|
||
|
|
|
||

|
|
https://<yourserver>/v2pssl/query/<CIDR block>
|
||
|
|
https://<yourserver>/v2pssl/cquery/<SHA1 certificate fingerprint>
|
||
|
|
https://<yourserver>/cfetch/<SHA1 certificate fingerprint>
|
||
|
|
~~~
|
||
|
|
|
||
|
|
Query values can be IP addresses or CIDR blocks between /32 up to /23:
