How to get a password encrypted since the Java Script file in my web application? <p>I'm designing some code for a standard login in a web application, I consider that doing the <strong>password encryption</strong> on <strong>client side</strong> is better than making mongo server doing it.</p> <p>So, if I have this code ...</p> <pre><code>$("#btnSignUp").click( function () { var sign = { user:$("#signUser").val(), pass:$("#signPass").val() }; }); </code></pre> <p>And then I'd do a <strong>post</strong> of <code>sign</code> with the password value already encrypted, how could I achieve this? Does JavaScript support AES?</p>
