Peace Protocol

Descrição

Peace Protocol enables WordPress site administrators to authenticate as their website and send cryptographically signed “peace” messages to other WordPress sites running the same protocol. This creates a decentralized network where admins can establish trust relationships, share peace, and enable cross-site interactions.

🔒 **Security-First Design**

Admin-Only Authentication

• WordPress Administrators Only: This plugin is designed exclusively for WordPress site administrators
• Site-Level Authentication: Admins authenticate as their website, not as individual users
• No Public Registration: No public user registration system – only federated users created after secure handshakes
• Cryptographic Tokens: Each site uses cryptographically secure tokens for authentication

Federated User System

• Limited Permissions: Federated users can only comment on posts, no admin access
• Automatic Cleanup: Federated users are removed when the plugin is uninstalled
• Role-Based Security: Federated users have the federated_peer role with minimal capabilities
• No Dashboard Access: Federated users cannot access WordPress admin areas

Token Security

• Cryptographically Secure: Tokens are generated using WordPress’s secure password generator
• Token Rotation: Support for multiple tokens with automatic rotation
• Secure Storage: Tokens are stored securely in WordPress options
• Expiring Authorization Codes: Authorization codes expire after 5 minutes

🚀 **How It Works**

For WordPress Administrators

1. Install & Activate: Install the plugin and activate it on your WordPress site
2. Generate Tokens: Go to Settings > Peace Protocol and generate authentication tokens
3. Send Peace: Use the peace button to send cryptographically signed peace to other sites
4. Build Network: Connect with other WordPress sites and build a network of trust

Federated Login Process

Peace Protocol Authentication

1. User from Site A visits Site B and wants to comment
2. User clicks “Peace” button on Site B
3. User chooses “Login with Peace Protocol” from the choice modal
4. Site B redirects to Site A for authentication
5. Site A validates the user and generates an authorization code
6. User is redirected back to Site B with the authorization code
7. Site B automatically logs in the user as a federated user from Site A
8. User can comment on Site B as “siteacom”

IndieAuth Authentication

1. User from Site A visits Site B and wants to comment
2. User clicks “Peace” button on Site B
3. User chooses “Login with IndieAuth” from the choice modal
4. Site B discovers IndieAuth endpoints on Site A
5. Site B redirects to Site A’s IndieAuth authorization endpoint
6. Site A validates the user and generates an authorization code
7. User is redirected back to Site B with the authorization code
8. Site B exchanges the code for an access token using PKCE
9. Site B automatically logs in the user as a federated user from Site A
10. User can comment on Site B as “Logged in as siteacom”

Security Flow

1. Cryptographic Handshake: Sites exchange cryptographically signed tokens
2. Token Validation: Each peace message is validated using secure tokens
3. Federated User Creation: Only after successful handshake are federated users created
4. Limited Permissions: Federated users have minimal permissions and no admin access
5. Automatic Cleanup: All federated data is removed on plugin uninstall
