Adds a rustdoc example which completely demonstrates how to use code
written generically with `ed25519::Signature` and `signature::{Signer,
Verifier}` with the concrete `ed25519_dalek::{Keypair, PublicKey}`
types.
Unlike the previous example, which hardly showed anything, this commit
also pulls in `ed25519-dalek` as a `[dev-dependency]`, which makes it
possible to actually doctest the example.
Adds a `ecdsa::verifier::Verifier` facade which handles parsing of
`PublicKey` and computing digests of messages, ala the `Signer` facade
added in #109.
The implementation is generic over the elliptic curve and digest
function, providing a `DigestVerifier` impl, and when the curve type
impls `DigestPrimitive`, a `Verifier` impl as well.
Adds a `ecdsa::signer::Signer` facade which handles parsing of
`SecretKey` data and zeroization of the private scalar.
The implementation is generic over the elliptic curve and digest
function, providing a `RandomizedDigestSigner` impl, and also when the
curve type impls `DigestPrimitive`, a `RandomizedSigner` impl.
Bumps the following crate dependencies, which all now depend on
`generic-array` v0.14:
- `elliptic-curve` v0.4.0
- `k256` v0.3.0
- `p256` v0.3.0
- `p384` v0.2.0
Also re-exports `generic-array` from the `elliptic-curve` crate rather
than depending on it directly, which simplifies upgrades.
