KryptoKoder provides a free online browser based PDF signature service that does not require a license to use. The service is still limited in the sense that it only allows up to two signers, each signer can only have one visible signature, and the visible signature consists of the signer's name. These limitations will be lifted in the near future.

To use the service the signer needs to install the MyPDFSigner-Tray application as explained in the Online Demo and use the default configuration. This application runs a local service that interfaces with the user's KeyStore (like a smart card, a USB token, the Windows Certificate Store or Apple Keychain).

The use case workflow is the following:
