VerifyCT од janspambox

VerifyCT is meant to help verify that TLS certificates served by web sites are correctly included in Certificate Transparency (https://certificate.transparency.dev/). It's a work-in-progress and currently only collects all certificates it sees, allows you to export them, and performs very basic SCT signature verification.
