rsa is not compatible with rand 0.8.0

[brmmm3]

If I update my dependency of rand from 0.7.3 to 0.8.0 I get the following error:

the trait bound rand::rngs::OsRng: rand_core::RngCore is not satisfied the trait rand_core::RngCore is not implemented for rand::rngs::OsRng note: required because of the requirements on the impl of rand::Rng for rand::rngs::OsRng

I'm using rsa 0.3.0.

This seems to require that num-bigint is updated to rand 0.8 first and I've added an issue in that project.

Still waiting a little bit longer to propagate this through libraries, breaking rand changes are quite painful and dividing in the ecosystem. Last time around it took months for the ecosystem to rally behind the latest version.

PR is here: #85 , requires upstream PR to be merged first.

We'll be bumping (most of) the rest of the RustCrypto to use rand_core v0.6 later this month / early next month so it's probably a good time to upgrade.

Definitely agree these are really painful upgrades, especially as rand is the most used crate in the entire Rust ecosystem, according to the "Most Downloaded" list on https://crates.io/

rand 0.8 support was added to num-bigint 0.4.0 so #85 is no longer blocked?
