Password rules for encrypting files

Aspose.PDF Product Family
1

My application encrypts PDF files with line:
EncryptFile(userPassword, ownerPassword, DocumentPrivilege.AllowAll, KeySize.x128, Algorithm.AES)

I got exception
Exception: System.IO.IOException: Bad password!: v5.6.0.0
at Aspose.Pdf.Kit.PdfFileSecurity.EncryptFile

The password looks like that ABC2EFG2016 .

Is that because the password format is not good? What are the rules on which password is valid?

Hi,

Thanks for contacting support.

The format of password appears to be fine because any string can be used to encrypt the document. The problem might be related to the structure and complexity of input document, so we need the input PDF file, so that we can test the scenario in our environment.

Furthermore, please note that Aspose.Pdf.Kit for .NET has been discontinued as a separate product and all its classes and enumerations are included in Aspose.Pdf.Facades namesapce of mergedAPI release of Aspose.Pdf for .NET. You may consider visiting [Migration from Aspose.Pdf.Kit](("[[BL]]https://docs.aspose.com/pdf/net/migration-from-aspose-pdf-kit/[[/BL]])

We are sorry for this inconvenience.
