2.x Series

  • Note: All x255919-dalek 2.x releases are in sync with the underlying curve25519-dalek 4.x releases.

2.0.1

  • Fix nightly SIMD build

2.0.0-rc.3

  • StaticSecret serialization and to_bytes() no longer returns clamped integers. Clamping is still always done during scalar-point multiplication.
  • Update underlying curve25519_dalek library to 4.0.0-rc.3. Notable changes:

2.0.0-rc.2

  • Update MSRV to 1.60.
  • Update edition to 2021
  • Add .as_bytes() and AsRef<[u8]> for Shared/StaticSecret
  • Add getrandom feature to provide random_from_rng constructors
  • Make StaticSecrets optional via feature static_secrets
  • Update underlying curve25519_dalek library to 4.0.0-rc.2. Notable changes:

2.0.0-pre.1

  • Loosen restriction on zeroize dependency version from =1.3 to 1.
  • Update MSRV to 1.51.

2.0.0-pre.0

  • Update rand_core dependency to 0.6.

1.x Series

1.2

  • Add module documentation for using the bytes-oriented x25519() API.
  • Add implementation of zeroize::Zeroize for PublicKey.
  • Move unittests to a separate directory.
  • Add cargo feature flags "fiat_u32_backend" and "fiat_u64_backend" for activating the Fiat crypto field element implementations.
  • Fix issue with removed feature(external_doc) on nightly compilers.
  • Pin zeroize to version 1.3 to support a wider range of MSRVs.
  • Add CI via Github actions.
  • Fix breakage in the serde unittests.
  • MSRV is now 1.41 for production and 1.48 for development.
  • Add an optional check to SharedSecret for contibutory behaviour.
  • Add implementation of ReusableSecret keys which are non-ephemeral, but which cannot be serialised to discourage long-term use.

  • Fix a typo in the README.

1.1.0

  • Add impls of PartialEq, Eq, and Hash for PublicKey (by @jack-michaud)

1.0.1

  • Update underlying curve25519_dalek library to 3.0.

1.0.0

  • Widen generic bound on EphemeralSecret::new and StaticSecret::new to allow owned as well as borrowed RNGs.
  • Add PublicKey::to_bytes and SharedSecret::to_bytes, returning owned byte arrays, complementing the existing as_bytes methods returning references.
  • Remove mention of deprecated rand_os crate from examples.
  • Clarify EphemeralSecret/StaticSecret distinction in documentation.

Pre-1.0.0

0.6.0

  • Updates rand_core version to 0.5.
