How to Sign a PDF

The following Bouncy Castle libraries must be downloaded (in their last available version):

Install an external Oxygen PDF Chemistry processor.

Restriction: A separate installation is required to include the additional libraries.
Copy the Bouncy Castle libraries to the [CHEMISTRY_INSTALL_DIR]/lib directory.
Create a keystore file (if you do not already have one). See Oxygen PDF Chemistry User Guide: Signing for information about how to create one.
Set the keystore file as the value for the chemistry.sign.keystore parameter.
Optional: If the keystore uses an export password, set it as the chemistry.sign.password value.
Optional: If you need to add more information (such as your company name), you can set the other chemistry.sign.* parameters.
Set the external Oxygen PDF Chemistry path as the value for css.processor.path.chemistry.
Run the transformation scenario.
