PdfEditorAddLongTermValidation Method

Adds the validation data of the signatures when the document is saved: the certificates and their revocation information, so the signatures can be validated after the certificates expire. Signatures that carry a signature timestamp reach the PAdES B-LT level or, when a timestamp server is set and a document timestamp is added over the validation data, the PAdES B-LTA level. The document timestamp also renews the protection of the signatures that already have one

public void AddLongTermValidation(
	PdfLongTermValidationOptions options
)

Parameters

options  PdfLongTermValidationOptions
The timestamp server and the additional trusted certificates

Remarks

The revocation information is downloaded from the URLs published in the certificates, so saving requires network access. A revoked signing certificate or a signature without revocation information makes the save fail, with the cause of each signature in the error message. Encrypted documents are not supported
