 ### How does it work?
-The GSA Document Signing Tool includes a simple, 508-compliant Graphical User Interface (GUI) to assist in the signing of your desired document. The tool allows the user to select the desired file they'd like signed, a field to enter the user's PIV application PIN , and a "Sign" button to initiate the signing. The tool automatically detects any smart card readers and PIV cards connected to the system. The tool utilizes PKCS#11 to interact with the reader and PIV card. The signed file is formatted in an enveloped PKCS#7 (.p7m) file, which is the required format for the OFR's document submission portal. In order for the tool to sign correctly, the PIV card MUST contain a valid digital signing certificate (i.e. Key usage of Digital Signature and Non-repudiation). If it doesn't contain a valid digital signing certificate, the application will provide a descriptive error messages.
