We are using iText to convert text files to PDF as outlined in the FAQ. This works; however I want to take a checksum of the PDF created and use it in conjunction with some other information to verify we have not created this file before. What I am finding, however, is that the metadata of the PDF always differs between iText versions as well as creation date/time, so I cannot create the exact same file twice and thus cannot rely on a checksum. I could use the checksum from the input file, except that this is a modification to a production application and we no longer have the input files for the existing data. So to do this I would have to extract the text to get an approximation of the original file. If I did this, the checksum would represent slightly different things from the old to the new data. What I am wondering about is whether these variable pieces of metadata are vital to the PDF structure, and if not, what would it take to remove them? Alternatively, if anyone has a better idea then those are welcome too.
