Edit onlineHow to Sign a PDF The following Bouncy Castle libraries must be downloaded (in their last available version): bcpkix-jdk18on bcprov-jdk18on bcutil-jdk18on 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.
