Changelog

v0.8.0

  • Implement Try and Increment when converting hash to scalar #128
    Improves performance and security of conversion 🔥
  • Get rid of deprecated rust-crypto dependency #137
    • Changed the crate providing merkle trees support: merkle-sha3 v0.1merkle-cbt v0.3
    • Merkle trees API has been slightly changed
    • Merkle trees are generic over hash function (it used to work with keccak256 only)
    • Merkle proofs built by previous versions of curv are incompatible with latest curv
  • Make the commitments generic over the hash function #129
    Allows the user to choose their own hash function when using our hash and related commitments
  • Unify and optimise bigint serialization #139
    • Bigints are serialized as bytes (instead of converting to hex/decimal format), that should save communication size (depends on serialization backend)
    • Different backends serialize bigints in the same way, ie. number serialized via rust-gmp backend will be properly deserialized via num-bigint backend and vice-versa
    • Compatibility notes: bigints serialization format is changed, so numbers serialized with older curv are not compatible with the newest version

v0.8.0-rc3

  • Fix point subtraction. Bug was introduced in v0.8.0-rc1. #127
  • Add Polynomial::lagrange_basis function #130
  • Katex <> Docs integration #131
    Allows using KaTeX in documentation comments. Math formulas will be properly rendered on docs.rs.
  • LDEI proof minor improvements #133
    Adds missing implementations of Clone and serialization traits.
  • Update hmac, digest, sha2,sha3 dependencies #134
    hmac: v0.7.1v0.11
    digest: v0.8.1v0.9
    sha2: v0.8.0v0.9
    sha3: v0.8.2v0.9

v0.8.0-rc2

  • Remove dependency on ring_algorithm crate #125, #124

v0.8.0-rc1

  • Elliptic curve API has been significantly changed #120

    In particular: ECPoint, ECScalar traits were redesigned. They remain, but are not supposed to be used directly anymore. In replacement, we introduce structures Point, Scalar representing elliptic point and scalar. See curv::elliptic::curves module-level documentation to learn more.

  • Add low degree exponent interpolation proof #119
