Hello,

I have a encrypted PDF file to stream using PDFHttpStream and using doc.OpenStream(stream, "PASSWORD");
always return -3 (damaged or invalid format)

but when loading the same file locally with password using doc.Open(URL, "PASSWORD") it works perfectly

is there any limitation on encrypted content on PDFHttpStream API? Thanks

PDFHttpStream is customized encrypt data.
this can be open only encrypted by PDFHttpStream.

PDF file encrypted by tools like Adobe Acrobat, just use normal method.
