Dear all,

I want to know the encryption and decrytion details of a PDF file. I have read PDF Specs for this purpose, but unable to figure out that how we can perform encryption / decryption in PDF document. It is done using a combination of MD5 & RC4 algorithms.

I DON'T KNOW, HOW IT IS DONE? If any one of you have ever experienced something similar, do let me know. Need attention of experts in PDF work space. I do not want to call some specific expert(A), as he told me once, not to mention a particular person. Thanks in advance.

Regards,

Shozi
