This free signing service is for demo/testing purposes only and powered by ADSS Signing Server (J2EE application).

ADSS Signing Server uses a flexible web services API (OASIS DSS and optimized HTML) to create exactly the type of signatures you need from your business applications. All the hassle of creating signatures, managing keys and ensuring highest levels of security is removed. Automated signing from an application, i.e. in unattended mode, is also easily achieved as well as unique signature key handling per user.

The ADSS server can utilize many different signing keys for different departmental units, groups or individual users. Strict identification and authentication, access control and authorization checks are performed to control client applications access to specific signing keys managed on the server.

If you are using your own file – note that we restrict the file size to a maximum of 1024 KB

In this demo we authenticate the signer using just a User ID and password, however the business application could use multiple user authentication options.
