This example shows how to load a password protected PDF and change its metadata. Keep in mind that in some cases metadata in a PDF may also be encrypted, in which case accessing it without the password is impossible. For reference, the loaded PDF is protected with the owner password 'owner' and user password 'user'.
DsPdf is compatible with .NET 6 or later, .NET Core 2.0 or later, .NET Standard 2.x, .NET Framework 4.6.1 or later. All features are supported on Windows, macOS and Linux.
