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 -v Print out verbose/debug info -c CONCURRENCY_COUNT The number of concurrent downloads to run at a time
