title: What implementions of Ed25519 exist?
body: <p>The <a href="https://www.grc.com/sqrl/sqrl.htm" rel="noreferrer">new SQRL authentication</a> scheme relies on Curve <a href="http://ed25519.cr.yp.to/index.html" rel="noreferrer">Ed25519</a> encryption developed by Daniel Bernstein. However, in order to start implementing this scheme there needs to be a mature implementation of Curve Ed25519 first.</p>
  
  <p>Does anyone know of any mature, implementations? For Java, .NET or any other popular platform?</p>
