Installation

npm install clydeio-hmac-auth --save

Configuration

Filter accepts the configuration properties:

• realm: A string that identifies the authentication realm.
• consumers: An object with the list of key properties and secret values.

Examples

Securing a provider

Here we are configuring a provider that is accessed for any URL that starts by: http://CLYDE_SERVER/context. The requests are redirected to http://some_server but before HMAC authentication is applied. The authentication realm is Provider's Realm and the only available user is those that signs request with the keyA and applying the secret secretA.

{
  "providers": [
    {
      "id": "provider",
      "context": "/context",
      "target": "https://some_server",
      "prefilters": [
        {
          "id": "hmac-auth",
          "path": "clyde-hmac-auth",
          "config": {
            "realm": "Provider's Realm",
            "consumers": {
              "keyA": "secretA"
            }
          }
        }
      ]
    }
  ]
}

Notes

• It must be configured as a global or provider's prefilter. It has no sense as a postfilter.
