Quick Start

1. Get Your API Key

Get API Key

2. Create Your First Master Key

javascript

// Create an organization master key
const response = await fetch('https://api.tenzro.com/ledger/keys/master', {
  method: 'POST',
  headers: {
    'X-API-Key': 'sk_your_api_key_here',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    name: "my-master-key",
    hierarchy_level: "organization",
    protection_level: "hsm",
    location: "us-central1",
    algorithm: "google_symmetric_encryption",
    organization_id: "org_12345"
  })
});

const masterKey = await response.json();
console.log('Master key created:', masterKey.master_key_id);

3. Derive and Use Child Keys

javascript

// Derive a child key for your service
const deriveResponse = await fetch('https://api.tenzro.com/ledger/keys/derive', {
  method: 'POST',
  headers: {
    'X-API-Key': 'sk_your_api_key_here',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    master_key_id: masterKey.master_key_id,
    derived_key_name: "my-service-key",
    derivation_context: "data_encryption",
    hierarchy_level: "service",
    kdf: "hkdf_sha256"
  })
});

const derivedKey = await deriveResponse.json();

// Encrypt sensitive data
const encryptResponse = await fetch('https://api.tenzro.com/ledger/encrypt/hsm', {
  method: 'POST',
  headers: {
    'X-API-Key': 'sk_your_api_key_here',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    plaintext: "Sensitive business data",
    key_id: derivedKey.derived_key_id,
    algorithm: "aes_256_gcm"
  })
});

const encrypted = await encryptResponse.json();
console.log('Data encrypted with derived key');
