Description

Hi,

I tried using the Signature example (https://svn.apache.org/viewvc/pdfbox/trunk/examples/src/main/java/org/apache/pdfbox/examples/signature/) which works great for certifying pdfs.

However if I want to certify and replace the original pdf without creating a new one (like foo_signed.pdf should only be foo.pdf), I get an exception:

`Exception in thread "main" java.io.IOException: Error: End-of-File, expected line pdfbox`

I invoked the method like this (L215 of CreateSignature.java):
`signing.signDetached(inFile);`

How would I change the example so that I can certify pdfs without creating copy files?
