-------------------------------------------------------------------

Need to do some housekeeping before resolving, some of the commits are missing 
in this ticket. Maybe svn2jira was down (again) without me noticing.

Also, keyStore parameter null is reported as "Provided decryption material is 
not compatible with the document" which is 🤦‍♂️

> Follow-up of PDFBOX-4413. AES256 works for public key crypto, but AES128 
> doesn't when the file is generated by an external software. (local tests 
> work) We should at least get the decryption to work.
