Hey everyone, I want to parse the CT logs and extract some fields like domains and all. How I can achieve this any tutorials or scripts ?

Say I want to get all the domains from these N certificates available in this argon2024 log.

https://ct.googleapis.com/logs/us1/argon2024/ has 2,202,566,278 certificates

Thanks in advance.

Hi Aayush,

All the structures used in RFC6962 logs are defined here. Here's a bunch of tools that allow you to fetch these entries, with various parsing capabilities depending on the libraries they use.

I hope that helps,
Philippe
