TimeStamp (TSA) partially implemented...

Open dgillier opened this issue 3 years ago • 4 comments

Hello,

Looks like TSA timestamping (I.e RFC-3161) is not implemented yet, some preliminary works has been done in 2014...

public function setTimeStamp($tsa_host='', $tsa_username='', $tsa_password='', $tsa_cert='') and protected function applyTSA($signature)

Any change to see this implemented ? Thanks, Denis

Hi everybody, Few years laters, it seems to be very complicated to have this applyTSA method progressing... Does anyone know how to go further for TimeStamping PDF with Free RFC3161 servers ? I have the signature valid, but not the timestamp. Please Help.

I have just tested the hidaw tcpdf fork, and he's right, it works properly. I have the embedded timestamp inside the signature.
