When looking at how this would generlaize to the other public key
cryptosystems (ECDSA, ED25519, etc.), I think having fewer submodules
involved makes more sense.
This is a step towards removing the heap-allocated and usually-unnecessary
`public_key: RsaSubjectPublicKey` field. The new API allows the caller to
better control how it stores/allocates the component values. This also removes
a couple of infallible `unwrap()`s.
This is a step towards removing `io::Positive` from the public API.
This is a breaking API change.
The newest Rust Nightly is getting stricter about `forbid(warnings)`
which breaks the build.
Use "deny" instead of "forbid". And only deny when running Clippy in
CI/CD, so that when hacking on *ring* we don't have to deal with
warnings right away; we now only have to deal with them when we're ready
to submit a change to be merged.
Run the RSA and signature tests in WebAssembly.
Implement Elem*Elem multiplication for platforms for which we have no assembly
language implementation of it. Refactor the code to accomodate this.
`elem_reduced` was infallible previously as it always ensured the prerequisites
for the reduction were met. Make this clear in the return type, as a side-effect
of the refactoring needed for implementing the multiplication.
This implementation is far from efficient. More work needs to be done to make it
faster.
Embed test data files into test executables so that file I/O isn't
necessary during tests. This allows the tests to run on platforms that
don't have file I/O. It also makes it easier to run the tests on a
separate (virtual) machine from the build machine since the test
automation no longer needs to keep track of the test files.
Switch to Rust 2018 Edition. Fix up some build breakage for different
configurations that were found in the process of testing this,
particularly `--no-default-features`.
I want to explore some new RSA functionality that might make `Clone`
difficult to implement, so I'm going to revert this change before
people start depending on it.
