TL;DR
33 |
34 | CertStream is an intelligence feed that gives you real-time updates from the Certificate
36 | Transparency Log network, allowing you to use it as a building block to make tools that react to new certificates being
37 | issued in real time. We do all the hard work of watching, aggregating, and parsing the transparency logs, and give you super simple
38 | libraries that enable you to do awesome things with minimal effort.
39 |
40 | It's our way of saying "thank you" to the amazing security community in general, as well as a
41 | good way to give people a taste of the sort of intelligence feeds that are powering our flagship
42 | product - PhishFinder.

60 |61 | CertStream is hosted on Github and we currently have libraries for Python, Javascript, Go, and Java. 62 | These libraries are intended to lower the barrier of entry to interacting with the Certificate Transparency Log network so you can craft simple but powerful analytics tools with just a few lines of code! 63 |

93 |CertStream CLI
98 | 99 |100 | Installing the CLI is easy, all you have to do is install the python library and run it like any other program. It can be used to emit certificate data in a number of forms to be processed by other command line utilities (or just for storage). Pipe it into grep, sed, awk, jq, or any other utility to send alerts, gather statistics, or slice and dice certs as you want! 101 |
