Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
I don't know what your ultimate goal is (learning how CT logs work? Implementing a client? Search a specific certificate?), but perhaps using sites like crt.sh (which gets its data from a lot of CT logs) is easier and faster, depending on your goal?
Why do you view the CT logs as any more "authoritative" than the sites that are serving those certificates? And why on earth would you want to do this in any event?
