Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog (modification: no type change headlines) and this project adheres to Semantic Versioning.

6.1.0 - 2019-02-12

First TypeScript based release of the library, now also including a type declaration file distributed along with the package published, see PR #170.

Bug Fixes

  • Fixed a bug in isValidSignature() not correctly returning false if passed an s-value greater than secp256k1n/2 on homestead or later. If you use the method signature with more than three arguments (so not just passing in v, r, s and use it like isValidSignature(v, r, s) and omit the optional args) please read the thread from PR #171 carefully and check your code.

Development

  • Updated @types/node to Node 11 types, PR #175
  • Changed browser from Chrome to ChromeHeadless, PR #156

6.0.0 - 2018-10-08

  • Support for EIP-155 replay protection by adding an optional chainId parameter to ecsign(), ecrecover(), toRpcSig() and isValidSignature(), if present the
    new signature format relying on the chainId is used, see PR #143
  • New generateAddress2() for CREATE2 opcode (EIP-1014) address creation (Constantinople HF), see PR #146
  • [BREAKING] Fixed signature to comply with Geth and Parity in toRpcSig() changing v from 0/1 to 27/28, this changes the resulting signature buffer, see PR #139
  • [BREAKING] Remove deprecated sha3-named constants and methods (see v5.2.0 release), see PR #154

5.2.0 - 2018-04-27

  • Rename all sha3 hash related constants and functions to keccak, see this EIP discussion for context (tl;dr: Ethereum uses a slightly different hash algorithm then in the official SHA-3 standard)
  • Renamed constants:
    • SHA3_NULL_S -> KECCAK256_NULL_S
    • SHA3_NULL -> KECCAK256_NULL
    • SHA3_RLP_ARRAY_S -> KECCAK256_RLP_ARRAY_S
    • SHA3_RLP_ARRAY -> KECCAK256_RLP_ARRAY
    • SHA3_RLP_S -> KECCAK256_RLP_S
    • SHA3_RLP -> KECCAK256_RLP
  • Renamed functions:
    • sha3() -> keccak() (number of bits determined in arguments)
  • New keccak256() alias function for keccak(a, 256)
  • The usage of the sha-named versions is now DEPRECATED and the related constants and functions will be removed on the next major release v6.0.0

5.1.5 - 2018-02-28

  • Fix browserify issue leading to 3rd-party build problems, PR #119

5.1.4 - 2018-02-03

  • Moved to ES5 Node distribution version for easier toolchain integration, PR #114
  • Updated isPrecompile() with Byzantium precompile address range, PR #115

5.1.3 - 2018-01-03

  • ES6 syntax updates
  • Dropped Node 5 support
  • Moved babel to dev dependencies, switched to env preset
  • Usage of safe-buffer instead of Node Buffer
  • Do not allow capital 0X as valid address in isValidAddress()
  • New methods zeroAddress() and isZeroAddress()
  • Updated dependencies

5.1.2 - 2017-05-31

  • Add browserify for ES2015 compatibility
  • Fix hex validation

5.1.1 - 2017-02-10

  • Use hex utils from ethjs-util
  • Move secp vars into functions
  • Dependency updates

5.1.0 - 2017-02-04

  • Fix toRpcSig() function
  • Updated Buffer creation (Buffer.from)
  • Dependency updates
  • Fix npm error
  • Use keccak package instead of keccakjs
  • Helpers for eth_sign RPC call

5.0.1 - 2016-11-08

  • Fix bufferToHex()

5.0.0 - 2016-11-08

  • Added isValidSignature() (ECDSA signature validation)
  • Change v param in ecrecover() from Buffer to int (breaking change!)
  • Fix property alias for setting with initial parameters
  • Reject invalid signature lengths for fromRpcSig()
  • Fix sha3() width param (byte -> bit)
  • Fix overflow bug in bufferToInt()

4.5.0 - 2016-17-12
