title: Does NPM support encryption of the _auth property in .npmrc?
body: <p>By using <code>npm adduser</code>, my credentials get stored as a base64-encoded String <code>username:password</code> into the <code>~/.npmrc</code> file:</p>
  
  <pre><code>_auth=aGV5OmN1cmlvdXM7LSk=
  </code></pre>
  
  <p>Anyone with access to this file could easily decode this and find out my password.</p>
  
  <p>Is it possible in NPM to encrypt the <code>_auth</code> value?</p>
