Limitations
Updated on Jun 3, 2026
The following limitations apply to digital signatures in RadPdfProcessing:
-
Export a signed document using a stream that supports reading. To ensure compatibility, always use a stream that supports both reading and writing when you export signed documents.
-
Signature validation depends on the bytes that represent the document. To validate a signature, the stream used to import the document must remain open.
-
The validation always runs for the current field, against the state of the document at the moment of import.
