Is there another way ? So that an external user does
not have to adjust his preference ? This makes no
sense to me - digital signature would be useless if
users without any technical knowledge actually have to
change default preference to see if a document
signature is valid.
Does the other options help ? Like :
/**
* The self signed filter.
*/
public static final PdfName SELF_SIGNED =
PdfName.ADOBE_PPKLITE;
/**
* The VeriSign filter.
*/
public static final PdfName VERISIGN_SIGNED =
PdfName.VERISIGN_PPKVS;
/**
* The Windows Certificate Security.
*/
public static final PdfName WINCER_SIGNED =
PdfName.ADOBE_PPKMS;
Does adobe have any standard trusted identities
installed ?
