In the “Secure PDF Files With a Password in C#, VB, and Java” article, we described how to use the PDFFile class from the PDF SDK to password protect and encrypt PDF files. Using the PDFFile class also makes digitally signing PDF files just as easy! The PDFFile class is available for .NET FX, .NET Core, and Java.
