Changelog

Entries are listed in reverse chronological order.

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

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:
  • curve25519-dalek backend now by default auto selects simd backend over serial where supported.

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:
  • curve25519-dalek backend additive features have been removed in favor of cfg based selection.
  • curve25519-dalek backend now by default auto selects the appropriate word size over the previous default 32.

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

• 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.

1.1.0

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

1.0.1

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.
