The Remote SIgnature API is a component that is installed in the signer's environment and can be accessed from a browser or a mobile device, for example. This component participates in the signature activation protocol (SAP) and generates the SAD. Provides the link between the signer and the signature process (linking the document to be signed, the remote signature key used by the signer to sign, and the data that authenticates the signer). Communicates with the SSA for the purpose of transferring the generated SAD to the SAM. Can be used alternatively to the SAK/OS.
