Remarks

The CrlClient class is the default ICrlClient interface implementation. Use the CrlClient object in the Pkcs7Signer instance constructor, as shown below:

using DevExpress.Pdf;
using DevExpress.Office.DigitalSignatures;
using DevExpress.Office.Tsp;

using (var signer = new PdfDocumentSigner("Document.pdf"))
{
    IOcspClient ocspClient = new OcspClient();
    ICrlClient crlClient = new CrlClient();

    // the freetsa client is used for demonstration purposes
    ITsaClient tsaClient = new TsaClient(new Uri(@"https://freetsa.org/tsr"), PdfHashAlgorithm.SHA256);

    // Create a PKCS#7 signature:
    Pkcs7Signer pkcs7Signature = new Pkcs7Signer("Signing Documents//testcert.pfx", "123",
     HashAlgorithmType.SHA256, tsaClient, ocspClient, crlClient, PdfSignatureProfile.PAdES_BES);

    // Create a new signature field:
    var signatureFieldInfo = new PdfSignatureFieldInfo(1);
    signatureFieldInfo.Name = "SignatureField";
    signatureFieldInfo.SignatureBounds = new PdfRectangle(10, 10, 150, 150);

    // Apply a signature with a new signature:
    var signature =
    new PdfSignatureBuilder(pkcs7Signature, signatureFieldInfo);

    // Sign and save the document:
    signer.SaveDocument("SignedDocument.pdf", signature);
}
