PDFEncrypt Description
PDFEncrypt is a open-source, free utility that encrypts PDF files using standard PDF algorithms. When a document's contents are encrypted, they become unreadable. A document can be decrypted by an authorized user to gain access to its contents. The user must enter the password to view a PDF document that is encrypted. PDFEncrypt allows you to encrypt PDF documents without having to buy Adobe Acrobat or upload confidential PDF files to a server. The app runs directly from your Windows PC. It allows you to specify the password (required for opening the document), as well as numerous options and permissions that can be applied to the PDF file.
