Limitations

Updated on May 13, 2026

There are a few limitations related to the usage of digital signatures in RadPdfProcessing.

• Exporting a document that is signed must be done using a stream that supports reading. To ensure compatibility, always use a stream that supports both reading and writing when exporting signed documents with Telerik.

• The validation of a signature depends on the bytes representing the document. Thus, to validate a signature, the stream, used to import the document, must be still open.

• The validation is always performed for the current field, against the state of the document at the moment of importing.
