The following example shows the placement of the method in the process of verifying the signatures on a SignedCms message. In this example, the message content is detached, so the message content must be verified independently of the SignedCms message.
// Create a ContentInfo object from the inner content obtained // independently from encodedMessage. ContentInfo contentInfo = new ContentInfo(innerContent); // Create a new, detached SignedCms message. SignedCms signedCms = new SignedCms(contentInfo, true); // encodedMessage is the encoded message received from // the sender. signedCms.Decode(encodedMessage); // Verify the signature without validating the // certificate. signedCms.CheckSignature(true);
