# Case study of existing CA certificates

- [CAcert](cacert.md)
- [Certum](certum.md)
- [D-Trust](dtrust.md)
- [GlobalSign](globalsign.md)
- [Letsencrypt](letsencrypt.md)
- [Sectigo](sectigo.md)

## Generating the Markdown/SVG files

1. Get the CA certificates of the CAs from their corresponding web sites
2. Run the generation script and filter through `pandoc` for better markdown layout

```shell
for dir in cacert certum dtrust globalsign letsencrypt sectigo
do
  poetry run python3 analyze_certs.py $dir | \
  pandoc -f markdown -t gfm > $dir.md
done
```
