🔐 Security Features

Certificate-Coupled Authentication

Our proprietary two-factor authentication system combines traditional JWT tokens with cryptographic certificate validation:

sequenceDiagram
    participant Client
    participant API
    participant Vault
    participant Keycloak

    Client->>API: Request + JWT + Certificate Signature
    API->>Keycloak: Validate JWT Token
    API->>Vault: Retrieve Certificate Public Key
    API->>API: Verify Digital Signature
    API->>Client: Authenticated Response

Loading

Key Benefits:

• 🔒 Defense in Depth: JWT compromise alone insufficient
• ✍️ Non-Repudiation: Cryptographic proof of request origin
• 🛡️ Anti-Theft Protection: Stolen credentials require both factors
• ⚡ Replay Prevention: Timestamp-based signature validation
