The Ecca First Party Certificate Authority is the CA that signs all your users' certificates.
It is the heart of the Eccentric Authentication Suite of programs. It makes it possible to eliminate passwords, secures communication, allows for private communication, and when applied correctly, even prevent phishing.
It's also way easier to operate than ordinary client certificate schemes. Especially when you use the ecca-proxy.
You can find example websites at: The worlds most secure dating site and The Favorite Number Site.
