Sign a PDF using SmartCard or HSM

Sign a PDF using SmartCard or HSM (Hardware Security Module) added in Limagito File Mover v2023.0.11.6

In this example we are going to a sign a PDF using a Smartcard or HSM (hardware security module).

  • As source we are going to use a Windows folder [WIN]:

  • Select the first Action ‘Load PDF to be signed’ and an extra tab will appear in the top menu bar. Select this ‘Pdf Load’ tab.

The default setup here is %SFP%SFN which translates to Source File Path and Source File Name. In most cases you don’t need to change this.

  • Back to the ‘Setup’ tab and select ‘Options for PDF signing’ in the Action list and next ‘Pdf Options’ Tab.
  1. Enable ‘Set Signing Certifcate V2 attribute’ (is enabled by default)
  2. Enable ‘Set Signing Time attribute’ (is enabled by default)

  • Back to the ‘Setup’ tab and select ‘Appearance of the PDF signature’ in the Action list and ‘Pdf Signature’ Tab.

We used the ‘Custom-JPG’ to add a custom logo at the left side of the signature. We also have a couple of built-in graphics available.

  • Back to the ‘Setup’ tab and select ‘Load certificate for PDF signing’ in the Action list and ‘Pdf Certificate’ Tab.

We are going to use a Smartcard or HSM (hardware security module) so we keep the ‘Certificate File’ field empty.

  1. Enable ‘Use load from Smartcard’
  2. Set the Smartcard CSP option
    • Load the certificate on the smartcard currently in the reader (or on the USB token).
    • Leave this field empty to allow us to automatically choose the CSP (Cryptographi Service Provider).
  3. Set the Smartcard PIN (password)
