You don't. You have to try each one, catch the exception, then try the
next. iText wasn't written with attempting multiple passwords on the
same PdfReader in mind. Yes, this means a lot of redundant IO and
computation. Can't be avoided at this time. If you'd like to alter
PdfReader's source so that it tries multiple passwords you provide, we'd
appreciate it if you could share your enhancement.
