From c43dd4d01b2344014004dff3834a86cd59e85adc Mon Sep 17 00:00:00 2001 From: David Robertson Date: Mon, 10 Jan 2022 13:40:46 +0000 Subject: [PATCH] Deal with mypy errors w/ type-hinted pynacl 1.5.0 (#11714) * Deal with mypy errors w/ type-hinted pynacl 1.5.0 Fixes #11644. I really don't like that we're monkey patching pynacl SignedKey instances with alg and version objects. But I'm too scared to make the changes necessary right now. (Ideally I would replace `signedjson.types.SingingKey` with a runtime class which wraps or inherits from `nacl.signing.SigningKey`.)
