Description

 
I am trying PDFBox for merging multiple PDF documents. Code is below. I am facing an issue. For a few PDF files i am getting "java.io.IOException: java.security.InvalidKeyException: Illegal key size". I am not sure what is going on. Could someone please help me ?

Could you please also let me know if PDFBox has restriction on PDFstandards/types etc ?
