A pure Rust multi-provider digital signature library which provides a thread-safe and object-safe API.
Presently implements the Ed25519 elliptic curve public-key signature system described in [RFC 8032] with software ([ed25519-dalek], [ring], [sodiumoxide]) and hardware ([yubihsm-rs]) providers available.
Signatory exposes a thread-and-object-safe API for creating digital signatures which allows several signature providers to be compiled-in and available with specific providers selected at runtime.
| [Cargo Feature] | Crate | Type | Signing | Verification |
|------------------------|-----------------|------|---------|--------------|
| dalek-provider | [ed25519-dalek] | Soft | 43 k/s | 17 k/s |
| ring-provider | [ring] | Soft | 31 k/s | 10 k/s |
| sodiumoxide-provider | [sodiumoxide] | Soft | 38 k/s | 14 k/s |
| yubihsm-provider | [yubihsm-rs] | Hard | ~8/s | N/A |
Above benchmarks performed using cargo bench on an Intel Xeon E3-1225 v5 @
3.30GHz with the nightly cargo feature enabled.
The [yubihsm-rs] crate depends on the aesni crate, which uses the new "stdsimd"
API (coming soon to stable!) to invoke hardware AES instructions via core::arch.
To access these features, you will need both a relatively recent Rust nightly and to pass the following as RUSTFLAGS:
RUSTFLAGS=-Ctarget-feature=+aes`
You can configure your ~/.cargo/config to always pass these flags:
toml
[build]
rustflags = ["-Ctarget-feature=+aes"]
