Missing package: cryptography #188

Package name: cryptography Issue type: Missing package Link to PyPI page: https://pypi.org/project/cryptography Link to piwheels page: https://www.piwheels.org/project/cryptography Version: 3.4+ Python version: 3.7 I am the maintainer: No More information:

Since moving to rust, we can't build this with only Debian rust packages installed. We need to bite the bullet and move to rustup.

I've seen this same issue on our side. FWIW, I'm temporarily fixed it in our usage by installing cryptography==3.3.2 in my virtual env before installing anything else. This works at least with the pre-2020 pip resolver, YMMV. 3.3.2 is the last version with a wheel in piwheels.

The builds for Buster succeeded yesterday: https://www.piwheels.org/project/cryptography/ Stretch builds are not available since v3.3, but at least for Raspberry Pi not important anymore?

That's odd. I started testing building this with rustup yesterday but I didn't install it on the builders yet (doing it right now).

Ah - it appears the maintainers lowered the Rust version requirement yesterday! https://github.com/pyca/cryptography/commit/151aa097cdf4632f382bc8c95d7771ed7290cf66

Lower the minimum supported Rust version (MSRV) to >=1.41.0. This change improves compatibility with system-provided Rust on several Linux distributions.

Ah well. Later we should have the missing versions too.

Update: using rustup on the builders isn't feasible due to https://github.com/rust-lang/rustup/issues/2383 so I've reverted back to using Debian's cargo. The latest cryptography builds ok so that'll have to do.

I may manually build and import the missing wheels if I get chance.
