curve25519-dalek unmaintained #63

I filed a PR against curve25519-dalek to update dependencies:

dalek-cryptography/curve25519-dalek#403

However, it appears that the crate is unmaintained and forces old dependencies all downstreams. There are numerous PRs requesting dependency updates that have all been ignored: https://github.com/dalek-cryptography/curve25519-dalek/pulls

I recommend we drop this curve OR make it optional until such time as a practical implementation can be made.

There's curve25519-dalek-ng, a fork that resulted from an internal drama, but the last release is actually older than curve25519-dalek.

An alternative would be to use BoringSSL (that supports X25519 and Ed25519).

We've had some previous requests to fork the dalek crates under @RustCrypto.

If that sounds interesting to you, it'd be helpful if you could leave a note about your use cases on this issue: RustCrypto/elliptic-curves#497

openpgp: Update rust-crypto dependencies
4ec75df 
  - Note: `x25519-dalek` is broken.  It depends on zeroize `=1.3`, but
    crates like rsa depend on newer versions of zeroize.

  - See WebAssembly/wasi-crypto#63 ,
    dalek-cryptography/x25519-dalek#92 .

  - Resolve this by using `x25519-dalek-ng`, which fixes this issue.
    This is a common workaround, and is also used by, for instance
    OpenMLS:

    https://github.com/openmls/openmls/blob/3ff090fd4881cb796d4688f7f174929a7521dbf1/openmls_rust_crypto/README.md?plain=1#L3

  - Fixes #910.
