Remarks

Important

For security reasons, do not set this property to SHA-1.

The code sample below shows how to set a PDF export file’s hash algorithm to SHA-512.

C#

using DevExpress.XtraReports.UI;
using DevExpress.XtraPrinting;
// ...
// Create a simple report.
XtraReport report = new XtraReport() {
  Name = "SimpleReport",
    Bands = {
      new DetailBand() {
        Controls = {
          new XRLabel() {
            Text = "Simple Report"
          }
        }
      }
    }
  }
};
// Use the SHA-512 hash algorithm.
report.ExportOptions.Pdf.SignatureOptions.HashAlgorithm = PdfHashAlgorithm.SHA512;
// Export the report to the user's Downloads folder.
report.ExportToPdf(Environment.GetFolderPath(Environment.SpecialFolder.UserProfile) + @"\Downloads\" + report.Name + ".pdf");

VB.NET

Imports DevExpress.XtraReports.UI
Imports DevExpress.XtraPrinting
' ...
' Create a simple report.
Private report As New XtraReport() With {
    .Name = "SimpleReport", .Bands = {
        New DetailBand() With {
            .Controls = {
                New XRLabel() With {.Text = "Simple Report"}
            }
        }
    }
}
}
' Use the SHA-512 hash algorithm.
report.ExportOptions.Pdf.SignatureOptions.HashAlgorithm = PdfHashAlgorithm.SHA512
' Export the report to the user's Downloads folder.
report.ExportToPdf(Environment.GetFolderPath(Environment.SpecialFolder.UserProfile) & "\Downloads\" & report.Name & ".pdf")
