Hi ericshliao,

I am by no means asking how to crack protected password. Maybe I didnt explain it correctly. Let me try again.

My friend sent me some of his pdf files. They have a digital signature on them. When I open them in Adobe reader or foxit reader on my desktop they just open without asking for any password or anything. They do show on the first page that they are digitally signed but when I try to open them in iliad to read the ipdf reader askes for password.

Now I was assuming that the digital signature is there on the document to stop others from changing the document but not to stop them from viewing it. If this is indeed the case then how come I cant view these document on iliad without giving a password? Is there any way of viewing the document on iliad or do I have to either (as you said) crack the proctected password or (as shaggy said) ask the friend for the password.

Please help ........
