[jira] [Commented] (PDFBOX-2729) Can't sign encrypted PDF files

    [ https://issues.apache.org/jira/browse/PDFBOX-2729?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15471294#comment-15471294 ] 

Tilman Hausherr commented on PDFBOX-2729:
-----------------------------------------

Unrelated but I'm trying to reach signature users:
Please have a look at PDFBOX-3065, this is about a different way to sign that will replace the current situation in 2.1, and in 2.0.* it will coexist. More explanation in {{PDDocument.saveIncrementalForExternalSigning}}, see [ https://svn.apache.org/r1759639 ].
