adding time to signatures
by Pablo Rodriguez 11 Dec '24

11 Dec '24

Hans, I found out why Acrobat isn’t reading time from signatures performed with ConTeXt. PAdES signatures require the /M key in the signature dictionary (https://www.etsi.org/deliver/etsi_en/319100_319199/31914201/01.02.01_60/en_…) Just in case you wonder, this has been a requirement in previous versions: https://www.etsi.org/deliver/etsi_en/319100_319199/31914201/01.01.01_60/en_… and https://www.etsi.org/deliver/etsi_ts/103100_103199/103172/02.02.02_60/ts_10…. Besides that, the CMS signature itself should not have any signing-time attribute. It might have a timestamp token as unsigned attribute added to the signature, as I already mentioned in my previous messages, but I’m still investigating this. BTW, there is an ongoing pull request to be able to have CMS signatures without signing time attribute in OpenSSL (https://github.com/openssl/openssl/pull/15783) But this still has to be merged (after being finished). The attached patch adds the /M entry in the signature dictionary. This is the best we (or at least I) can do right now. Many thanks for your help, Pablo

(btw, fwiw using \relax as sentinal is faster because there is no pushback needed and and internally - as macro body - a ; or \relax takes the same amount of memory and i suppose most goes into macros but performance and memory consumption is a topic on its own and probably very different between macro packages) >>>> one should also make sure an expression doesn't scan ahead, if only >>>> because it will expand whats coming next; basically \relax or matching >>>> () should have been mandate and it's a design flaw. >>> >>> Arguably yes but e-TeX was finalised in 1999 - that was an discussion >>> for a previous millennium (at least from a plain/LaTeX point of view) :) >> >> as much of tex .. > > Indeed - I know you have a different view on how to handle that than the > LaTeX one :) the fact that there was never a fundamental follow-up etex (language wise) kind of tells a story i guess but let's not waste time on that Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

LuaMetaTeX accepts `;` as part of `\numexpr`, which breaks LaTeX3
by Vítek Starý Novotný 06 Nov '24

06 Nov '24

Dear ConTeXt developers, since TeX Live 2024, LaTeX3 can no longer be used with LuaMetaTeX. [1] The issue seems to be that unlike e-TeX and LuaTeX, LuaMetaTeX accepts `;` as part of `\numexpr`. Since `;` is commonly used as a delimiter in LaTeX3, this is a significant issue. The issue would be best solved in LuaMetaTeX by sticking to just `%` like e-TeX and LuaTeX do. Would that be an option? [1]: https://github.com/latex3/latex3/issues/1518 Best, Vitek

alternate descriptions
by Pablo Rodriguez 28 Sep '24

28 Sep '24

Hans, many thanks for having added the alternate descriptions functionality to ConTeXt. I attach the patch, since the entry reads /AltText instead of /Alt. At least, /Alt is the right value in PDF-1.7 (https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/PDF32000_2008…) I cannot check PDF-2.0, but it would be weird to break backward-compatibility here. Many thanks for your help, Pablo
