latest der and pkcs1 inside rsa

[neuronetio]

Hi,
I have to use rsa with the latest der and pkcs1 packages.
Packages are ready, but rsa uses old versions.
When can I expect an updated version?
Thanks

A proper upgrade will involve switching from pkcs1 traits to the pkcs8 traits and using the pkcs1/pkcs8 feature.

This is because the blanket impls were reversed so the pkcs1 traits are blanket impl'd for types which impl the pkcs8 traits. Reversing the relationship allows for more than one blanket impl, which was used in this release to add sec1 support to types which impl the pkcs8 traits.

Also note that the new releases of der, pkcs1, and pkcs8 are all 2021 edition crates, so it would be best to update them when the rsa crate is ready to do an edition bump as well.

@tarcieri can you take a stab at this when you have a moment? I tried, but I got lost in the traits between pkcs1 and pkcs8 :/

Yep. See the comment I left here: #122 (comment)
