Start Tessera

Prerequisites​

Tessera installed

Start Tessera and send a payload​

The following example starts the transaction manager and local enclave.

1. Generate keys​

Generate a key pair in files called myKey.pub and myKey.key:

tessera -keygen -filename myKey

When prompted to enter a password, press Enter to generate an unlocked key.

Warning

This example uses unlocked keys for educational purposes only. Secure private keys appropriately in production environments.

2. Create a configuration file​

Create a file called config.json and add the following properties:

Tessera configuration file
{
  "useWhiteList": false,
  "jdbc": {
    "username": "sa",
    "password": "",
    "url": "jdbc:h2:./target/h2/tessera1",
    "autoCreateTables": true
  },
  "serverConfigs": [
    {
      "app": "ThirdParty",
      "serverAddress": "http://localhost:9081"
    },
    {
      "app": "Q2T",
      "serverAddress": "unix:/tmp/test.ipc"
    },
    {
      "app": "P2P",
      "serverAddress": "http://localhost:9001",
      "sslConfig": {
        "tls": "OFF"
      }
    }
  ],
  "peer": [
    {
      "url": "http://localhost:9001"
    },
    {
      "url": "http://localhost:9003"
    }
  ],
  "keys": {
    "passwords": [],
    "keyData": [
      {
        "privateKeyPath": "myKey.key",
        "publicKeyPath": "myKey.pub"
      }
    ]
  },
  "alwaysSendTo": []
}
