Question

是否有可以在PDF中输入密码的工具或DLL？

示例我有1,000个PDF文件我想在每个PDF上设置密码？每个文件的密码都不同。

使用Gnostice PDFOne .NET可以做到这一点。

Docotic.Pdf library可用于使用密码保护PDF文件。

以下是您的任务的示例代码：

Dim filesToProcess As String()
' populate filesToProcess somehow

For Each fileName As String In filesToProcess
    Using pdf As New PdfDocument(fileName)
        ' use OwnerPassword property if you need to protect file from being modified 
        ' use UserPassword property if you need to protect file from being modified and from being viewed without knowing the password
        pdf.UserPassword = "password"

        ' there is also another supported encryption algorithms
        pdf.Encryption = PdfEncryptionAlgorithm.Aes128Bit

        Dim savePath As String = fileName & "encrypted.pdf"
        pdf.Save(savePath)
    End Using
Next

您还可以setup permissions查看任何受保护的PDF文件。
