DevExpress.XtraPrinting.PdfSignatureOptions.DefaultHashAlgorithm = PdfHashAlgorithm.SHA512;
// Creates a simple report.
XtraReport report = new XtraReport()
{
    Name = "SimpleReport",
    Bands = {
        new DetailBand() {
            Controls = {
                new XRLabel() {
                    Text = "Simple Report"

report.ExportToPdf(Environment.GetFolderPath(Environment.SpecialFolder.UserProfile)
    + @"\Downloads\" + report.Name + ".pdf");

VB.NET

Imports DevExpress.XtraReports.UI

DevExpress.XtraPrinting.PdfSignatureOptions.DefaultHashAlgorithm = PdfHashAlgorithm.SHA512
' Creates a simple report.
Dim report = New XtraReport()
Dim band = New DetailBand()
Dim control1 = New XRLabel() With {
    .Name = "Label1",
    .Text = "Simple Report"
}
band.Controls.AddRange(New XRControl() {control1})
report.Bands.Add(band)
' Exports the report to the Downloads folder.
