示例1: Timestamp
// in case we just want to timestamp the file
public bool Timestamp (string fileName)
{
try {
AuthenticodeDeformatter def = new AuthenticodeDeformatter (fileName);
byte[] signature = def.Signature;
if (signature != null) {
Open (fileName);
PKCS7.ContentInfo ci = new PKCS7.ContentInfo (signature);
pkcs7 = new PKCS7.SignedData (ci.Content);
byte[] response = Timestamp (pkcs7.SignerInfo.Signature);
ASN1 ts = new ASN1 (Convert.FromBase64String (Encoding.ASCII.GetString (response)));
// insert new certificates and countersignature into the original signature
ASN1 asn = new ASN1 (signature);
ASN1 content = asn.Element (1, 0xA0);
if (content == null)
return false;
ASN1 signedData = content.Element (0, 0x30);
if (signedData == null)
return false;
// add the supplied certificates inside our signature
ASN1 certificates = signedData.Element (3, 0xA0);
if (certificates == null) {
certificates = new ASN1 (0xA0);
signedData.Add (certificates);
}
for (int i = 0; i < ts[1][0][3].Count; i++) {
certificates.Add (ts[1][0][3][i]);
}
// add an unauthentified attribute to our signature
ASN1 signerInfoSet = signedData[signedData.Count - 1];
ASN1 signerInfo = signerInfoSet[0];
ASN1 unauthenticated = signerInfo[signerInfo.Count - 1];
if (unauthenticated.Tag != 0xA1) {
unauthenticated = new ASN1 (0xA1);
signerInfo.Add (unauthenticated);
}
unauthenticated.Add (Attribute (countersignature, ts[1][0][4][0]));
return Save (fileName, asn.GetBytes ());
