You can use the Web Application Management Console to encrypt all settings in the Hyland.Web.PdfPop element. When encrypted, information such as the PDFPop username and password values cannot be viewed within the Web Server's Web.config file.
Encryption is enabled by the Encrypt PdfPop setting in the Web Application Management Console. When this setting is applied and saved, information within the Hyland.Web.PdfPop element is replaced with an EncryptedData element, which contains the encrypted settings.
For information about using the console to modify and encrypt PDFPop settings, refer to the Web Application Management Console module reference guide.
