SignedCms.Decode Method

This method resets all member variables of the object by using the information obtained from successful decoding.

The following example shows the placement of the Decode method in the process of verifying the signatures on a SignedCms message. In this example, the message content is not detached, so the message content is included in the SignedCms message.

// Create a new, nondetached SignedCms message.
SignedCms signedCms = new SignedCms();

// encodedMessage is the encoded message received from 
// the sender.
signedCms.Decode(encodedMessage);

// Verify the signature without validating the 
// certificate.
signedCms.CheckSignature(true);

The following example shows the placement of the Decode 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);
