PdfSignatureContent Methods

The PdfSignatureContent type exposes the following members.

Methods

	Name	Description
	GetHash	Gets the hash over which the signature was computed, if the hash is contained in the PdfSignatureContent; otherwise, . If the PdfSignatureContent is a DER-encoded CMS binary data object and conforms to RFC 5652 Cryptographic Message Syntax, the hash is either the value of the encapContentInfo field within the SignedData (if eContent field within the EncapsulatedContentInfo is not empty, in which case hashAlgorithm is SHA1 because the PdfSignatureContent is in the PKCS7_SHA1 format) or the value of the MessageDigest signed attribute (if present). If the PdfSignatureContent is a TimeStampToken as specified in RFC 3161 as updated by RFC 5816, the hash is the value of the messageImprint field within the TimeStampToken.
	GetRawData	Gets the copy of raw data of a PdfSignatureContent.
	ToString	Returns a String that represents this PdfSignatureContent instance. (Overrides ObjectToString)
