Email a existing pdf file with password protection

I have created a pdf using itextsharp. The requirement is that while sending the PDF as attachment in an email and it should be password protected.

I know that we can make a pdf password protected while creating it using itextsharp.

Is there any way to make an existing pdf password protected?

Use PdfReader in combination with PdfStamper and the setEncryption() method.

In Java, see encryptPdf() in this example: http://itextpdf.com/examples/iia.php?id=219

In C#, see EncryptPdf() in this example: http://kuujinbo.info/iTextInAction2Ed/index.aspx?ch=Chapter12&ex=EncryptionPdf
