Hi,

This time the lmtx upload has a (for some maybe) interesting new 
features: runtime pdf encryption.

context
    --ownerpassword=foo
   [--userpassword=bar]
   [--permissions="see context --help --expert"]

One can also use the document banner line, like:

% ownerpassword="foo" userpassword="" permissions="print,extract,quality"

Now, this is a feature that relies on the viewer to deal properly with 
it as we only support the not depricated method (why bother with the old 
stuff).

acrobat  : it took some effort (and trial and error) to make that one 
happy but it seems to work ok

summatra : the one i use, it works ok in the latest greatest (i use 
3.3.13418)

mutool   : okay but sometimes with a warning (i have a workearound but 
not enabled it because i consider it to be a bug)

qpdf     : happy but check gives a permissions warning (understandable 
as that is a real mess)

firefox  : opens ok in the latest version (pdf.js)

chrome   : can't handle the revision level we use (the rest is 
depricated so i consider it a lack of feature for now)

edge     : idem

okular   : my (windows) version is too old

xpdf     : not up to it yet

foxit    : (i never use it, but tried ... it's code seems to be what is 
used in chrome) doesn't work with this revision

I would be surprised if the native apple viewer works but I can't test that.

Given earlier pdf threads, I wanna check with Michal Vlasák what can be 
improved.

Performance is okay, the luametatex manual takes 1% more runtime and 
that's within the runtime measurement margin that I use. I didn't test 
with external images yet but will do that so don't expection yet. It 
will probably take a few months to reach a stable state anyway. (But ... 
afaiks tikz pdf generation, which is also somewhat alien to context, 
seems to work).

Hopefully I didn't mess up the unrelated code,

Hans
