From 90403b5e3c1135cbf319313ebbb737f9db5d34aa Mon Sep 17 00:00:00 2001 From: KnifeLemon Date: Wed, 4 Nov 2026 13:49:20 +0900 Subject: [PATCH] Read signed .p7m files as the file inside them (#1010) A .p7m is a CMS / PKCS #7 SignedData envelope (Italian e-invoices *.xml.p7m, signed PDFs *.pdf.p7m). The new built-in "p7m" engine takes the signed file out with SignedCms (DER, BER, Base64 or PEM; envelopes signed again are opened again, at most 8 deep; at most 512 MB). The signature is not verified or trusted: no chain, no revocation, no network. The format inside comes from the inner name (invoice.xml.p7m) or the first bytes. A new IEnvelopeOpener lets JobQueue ask for it before planning, and RoutePlanner.PlanThrough opens the envelope first and plans on from there, so P7M -> PDF -> PNG and P7M -> XML -> JSON are one conversion. Outputs are named after the file inside (invoice.pdf.p7m -> invoice.pdf). p7m is a read-only document input graded general; the documents donut learns it (schema 66). New strings are in all 20 languages.
