Prima guide pdf password crack (encryption key crack)

If anyone has trouble with the awful Prima PDF reader (it’s incredibly slow), just locate the PDF file from the program files entry of the guide. It is open-password protected. Fortunately, for now they use 40-bit encryption, which is no problem for
“Advanced PDF Password Recovery v5 0 Pro DOA rar”
Pass key found in ~12 hours of processing on my PC. Enterprise version of the soft could do it in some minutes, ElcomSoft claims.

Btw. – the developers/sellers of the password recovery programs maybe should rethink their selling model. Now they try to sell a program that does crack passwords, for a relatively high price (price range 49eur – 399eur for this particular product). As most users (like myself) need to crack just 1 document, or some documents at most, it would be nice to have an option that cracks a password/key for a given document, for a smaller price (5 euros or so). I mean they can now use cloud computing solutions like Amazon EC2
The only problem with the model is that password protected documents are usually sensitive – which was not the case here.
