Harvester of certificates, bearer of flannel.
Axeman is a utility for downloading, parsing, and storing Certificate Transparency Lists using python3's concurrency and multi-processing. Its aim is to download and parse certificates relatively quickly and efficiently, storing them in CSVs on the local filesystem.
Installation should be super straight forward, but you need a newer version of python (3.5+) to run it.
pip3 install axeman
$ axeman -h
usage: axeman [-h] [-f LOG_FILE] [-s START_OFFSET] [-l] [-u CTL_URL]
[-o OUTPUT_DIR] [-v] [-c CONCURRENCY_COUNT]
Pull down certificate transparency list information
optional arguments:
-h, --help show this help message and exit
-f LOG_FILE location for the axeman log file
-s START_OFFSET Skip N number of lists before starting
-l List all available certificate lists
-u CTL_URL Retrieve this CTL only
-o OUTPUT_DIR The output directory to store certificates in
