# Keychain - Zero Trust Data Security SDK

## Company Overview

Keychain provides a vertically-integrated Zero Trust SDK that shifts security from networks to the data layer itself. Our solution enables developers to build applications with embedded cryptography, self-sovereign identity, and dynamic access control - all in a lightweight 16MB SDK.

## What We Do

We solve the fundamental problem of data security in the digital world. While traditional security focuses on protecting networks and channels, Keychain protects the data itself through:

- **Data-centric security**: Every piece of data is encrypted and signed at creation
- **Self-sovereign identity**: Decentralized identities (DIDs) replace centralized certificate authorities
- **Dynamic access control**: Grant or revoke access to encrypted data without re-encryption
- **Offline-first architecture**: Full functionality without network connectivity

## Core Products

## Developer Integration

### For Robotics & Embedded Systems
```cpp
// Initialize robot identity
keychain::persona robot("robot_001_did");

// Authenticate sensor data
sensor_data = read_lidar();
auto signed_reading = robot.sign(sensor_data);

// Secure robot-to-robot communication
auto encrypted_cmd = robot.encrypt(command);
robot.add_decrypt_access(encrypted_cmd, "robot_002_did");

// Verify control commands
bool valid = keychain::verify(remote_cmd, signature, "operator_did");
if (valid) execute_command(remote_cmd);
```

### For AI Agents via Gateway API
```python
# Initialize agent with Keychain Gateway
agent = KeychainGateway(api_key="...", agent_did="agent_001")

# Secure agent-to-agent messaging
encrypted_msg = agent.encrypt(
    data={"task": "analyze", "target": "dataset_123"},
    recipient="agent_002_did"
)

# Issue verifiable credential to sub-agent
credential = agent.issue_credential(
    subject="sub_agent_did",
    claims={"permission": "read", "expires": "2024-01-01"}
)

# Create multi-agent consensus
transaction = agent.create_transaction(
    action="deploy_model",
    required_approvers=["agent_002", "agent_003"]
)
```
