-# Suppress alerts for weak cryptographic algorithms. The PDF file
-# format used to rely on various weak algorithms. It is no longer
-# necessary to use them when creating encrypted PDF files, but qpdf
-# must always retain support for those algorithms in order to be able
-# to read older files. qpdf issues warnings to try to prevent users
-# from creating new files with weak encryption algorithms.
