Question

I need to make a signature to pass as param into a jQuery $.post AJAX request, but I have some values to be hashed into Javascript vars. Any way to do it in an ERB file? Example:

var signature = '<%= Digest::MD5.hexdigest "app_key" + form params + "secret" %>

Answer 1

This normally will be done in client side

var signature = md5('app_key' + form_params + 'secret');

md5 is function from other javascript library like md5.js
