### Generate Security Token for Constellix API (JavaScript)

Source: https://api-docs.constellix.com/index

This script generates a security token required for authenticating with the Constellix API. It takes API and Secret keys from environment variables, calculates an HMAC-SHA1 hash based on the current timestamp and the secret key, and combines them into a single token string. This token is then set as an environment variable for use in subsequent API requests.

```javascript
var apiKey = postman.getEnvironmentVariable("apiKey");
var secretKey = postman.getEnvironmentVariable("secretKey");
function epochTime() {
    return new Date().getTime() + '';
}
postman.clearEnvironmentVariable("x-cns-security-token");
var time = epochTime();
var hmac = CryptoJS.HmacSHA1( time, secretKey ).toString( CryptoJS.enc.Base64 );
var token = apiKey + ":" + hmac + ":" + time;
postman.setEnvironmentVariable( 'x-cns-security-token', token );
```

### Constellix DNS API Authentication

Source: https://api-docs.constellix.com/index

Details on how to authenticate requests to the Constellix DNS API using API keys, Secret Keys, and HMAC-SHA1.

```APIDOC
## Authentication and Security Headers

Authentication with the Constellix API is performed using the API and Secret keys, provided on a per-user basis.

### Security Headers
- `x-cnsdns-apiKey`: Your Constellix API key.
- `x-cnsdns-requestDate`: The timestamp of the request in epoch milliseconds.
- `x-cnsdns-hmac`: The Base64 encoded HMAC-SHA1 hash of the request timestamp and your Secret Key.

Alternatively, these headers can be combined into a single header:
- `x-cns-security-token`: Concatenation of `apiKey:hmac:requestDate`.

### Example Security Token Generation (Postman)
```javascript
var apiKey = postman.getEnvironmentVariable("apiKey");
var secretKey = postman.getEnvironmentVariable("secretKey");

function epochTime() {
    return new Date().getTime() + '';
}

postman.clearEnvironmentVariable("x-cns-security-token");
var time = epochTime();
var hmac = CryptoJS.HmacSHA1( time, secretKey ).toString( CryptoJS.enc.Base64 );
var token = apiKey + ":" + hmac + ":" + time;
postman.setEnvironmentVariable( 'x-cns-security-token', token );
```
