Hi Leonard ! > Certs have to be in ASN.1 Yes, of course !
But what about the array ? I miss the info of how to build the 'array' holding the certificates. In Julien's example the CERT object contains a PDFString, not a PDFArray. The PDFString is a stream of ASN.1 encoded certificates, afai can guess from the code. But this doesn't seem to be the way the Reader expects it to be done ...
