Caramel is a certificate management system that makes it easy to use client certificates in web applications, mobile applications, embedded use and other places. It solves the certificate signing and certificate management headache, while attempting to be easy to deploy, maintain and use in a secure manner.
Caramel makes it easier (it’s never completely easy) to run your own certificate authority and manage and maintain keys and signing periods.
Caramel focuses on reliably and continuously updating short-lived certificates where clients (and embedded devices) continue to “phone home” and fetch updated certificates. This means that we do not have to provide OCSP and CRL endpoints to handle compromised certificates, but only have to stop updating the certificate. This also means that expired certificates should be considered broken.
