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) and hardware (yubihsm-rs) providers available.
About
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.
Provider Support
cargo features are used to select which providers are compiled-in:
Ed25519 providers
dalek-provider
*: provider for the ed25519-dalek crateyubihsm-provider
: provider for the yubihsm-rs crate supporting YubiHSM2 devices
* Enabled by default
YubiHSM2 Provider Notes
The yubihsm-rs crate depends on the aesni
crate, which uses the new "stdsimd" API
(which recently landed in nightly) 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:
[]
= ["-Ctarget-feature=+aes"]
