  See how simple it is to sign ANY File
Zero Footprint Client-side Signing using GoSign

This demo allows you to sign any file document using a standard browser and locally-held signing keys (e.g. on a smartcard or Windows Keystore). If you currently don't have a digital certificate you can obtain one in step1 below. 
 
 
Step 1: Get a certificate:
If you don't have a locally-held signing certificate, you can request a free one from the Ascertia CA from here. Follow the process until you have successfully created a certificate and then return to this demo.
Step 2: Select your document:
Use a standard contract.txt document already held on the server
Use my own document, which I will upload (see note below on restrictions on document size):
  File Path:   
               
Step 3: Select your signature format and type:

Notes
The advantage of this solution is that any file using locally-held keys (smartcard/token or soft signing keys).
In case you are uploading your own file, in this demo we restrict the file size to 500KB.
If a strong user-authentication is required but you do not wish to deploy keys in the shape of smartcards or tokens to your users.
