0Cert Wordpress Plugin - Rating, Reviews, Demo & Download
Plugin Description
0Cert replaces traditional SSL certificate authorities with Certificateless Public Key Cryptography (CL-PKC). Instead of trusting one of 150 certificate authorities, your domain name IS your cryptographic identity.
This plugin adds 0Cert protection to any WordPress site in minutes — no server configuration required.
What it does:
- Adds
X-0Cert-*verification headers to all pages - Serves the
/.well-known/0certendpoint that 0 Browser checks automatically - Verifies your keys against the Key Generation Center (KGC) on setup
- Shows your 0Cert status in the WordPress admin
What visitors see:
Users of 0 Browser (iOS) see a green 0Cert Verified badge when visiting your site instead of the standard SSL lock icon. Your site’s identity is cryptographically bound to your domain — not just promised by a certificate authority.
How it works:
- You register your domain at app.0cert.io or in the 0 Browser iOS app
- A Key Generation Center issues a partial key for your domain
- You generate your own user secret locally (never shared with anyone)
- The two combine into a full private key — even the KGC cannot decrypt your traffic
- Install this plugin, paste your keys, save — done
Zero configuration required:
- No server-level changes needed
- No DNS certificate records to manage
- No annual renewals
- Works on any WordPress hosting
Open source:
The full protocol, KGC server, iOS browser, and this plugin are all open source at github.com/0cert.
