About Cert Logik

What is Cert Logik?

Cert Logik is a collection of PKI and SSL products developed by Red Kestrel Consulting Limited. We've combined a CSR Decoder and X.509 Certificate Decoder into a single decoder to make decoding simpler. We've developed an SSL Checker that connects to your website and checks the installation of your SSL certificate. We have also developed a number of PKI and SSL standalone commercial tools.
