There is something off with nostr:npub1exv22uulqnmlluszc4yk92jhs2e5ajcs6mu3t00a6avzjcalj9csm7d828

They are very elusive about digitally signing their releases, only with recent updates here: https://github.com/simplex-chat/simplex-chat/issues/3158 that really don't add much.

In theory mobile releases are signed but can't find the signatures, definitely not alongside their binaries. Keys? Oh go find them at openpgp.org. Like where exactly? https://keys.openpgp.org/search?q=simplex yields no results. Also, no reproducible builds.

So, "quantum resistant E2E encryption" but not a single PGP signature?
