Take the output and add it as secure environment variables in your *.travis.yml* file.
```yml

node_js:
    - 0.8
env:
    global:
        - secure: "XqJtWxYjtjhRO3LzC/iBGLawDP+f/dL6kcUfDzDJPSKhdnXIRQgBE65g58hf1bPh4YowxuyPUnpK5pq6+frYQ6zNsW0AWBMa2dUP1FdSIxdCJNa3UHlMLYhqqECuVvev9A9NCijKBkuOOA+OvNgq9NIQsiS4g+dsaAlpuE72MYc="
```

##### using --add to populate .travis.yml
```bash
travis-encrypt --add -r pwmckenna/node-travis-encrypt ENV1=VALUE1 ENV2=VALUE2
> Wrote 2 blob(s) to .travis.yml
```

## Module
```js
var encrypt = require('travis-encrypt');
encrypt('pwmckenna/node-travis-encrypt', 'EXAMPLE_ENV_VARIABLE=asdf', function (err, blob) {
  // do something with the encrypted data blob...
});

// also supports encrypting for private travis pro repos,
// though it needs your github credentials to login to travis pro.
encrypt('pwmckenna/private-repo', 'EXAMPLE_ENV_VARIABLE=asdf', username, password, function (err, blob) {

});
```
