Enum PdfSignatureIntegrityStatus
The document-integrity axis of signature validation: whether the signed bytes still match the signature, independent of who signed.
public enum PdfSignatureIntegrityStatus
Fields
Valid = 0The digest and signature verify over the signed byte ranges.
DocumentModified = 1The signed bytes no longer match the signature: the document content was modified.
UnsupportedSubFilter = 2The signature uses a container format this version does not verify (for example a legacy PKCS#1 subfilter or a document timestamp).
MalformedSignature = 3The signature container is structurally broken or violates its byte-range contract.
SignerCertificateMissing = 4The container carries no signer certificate, so the signature cannot be checked.
