I would have expected to see at least some of their source code on Github (<a href="https:&#x2F;&#x2F;github.com&#x2F;Crypho" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Crypho</a>), especially the client-side where the private key and passphrase are handled (as described at <a href="https:&#x2F;&#x2F;www.crypho.com&#x2F;security.html" rel="nofollow">https:&#x2F;&#x2F;www.crypho.com&#x2F;security.html</a>). Without being able to inspect the source, why should anyone trust this company more than, say, Google or Facebook?
