I have some doubt in PDF Encryption dictionary entries.
In case a null string is specified for Owner and User password, the entry for 'O' and 'U' in Encryption Dictionary should be same for all PDF documents that are created who have null for the passwords correct ?
The PDF spec tells us to use MD5 hash fn for creating the encryption key, I have got a demo version from RSA, but I did not find anything like MD5 hash, its only MD5. Are both of them same ?
Thanks a lot!
