Release Notes

ethereumjs/ethereumjs-util

v7.0.7

Compare Source

• Removed stateRoot check for Account.isEmpty() to make emptiness check EIP-161 compliant, PR #​279
• Added type AddressLike and helper bnToHex(), PR #​279
• Added account.raw() which returns a Buffer Array of the raw Buffers for the account in order, PR #​279

v7.0.6

Compare Source

New Account class

This release adds a new Account class intended as a modern replacement for ethereumjs-account. It has a shape of Account(nonce?: BN, balance?: BN, stateRoot?: Buffer, codeHash?: Buffer).

Instantiation

The static factory methods assist in creating an Account object from varying data types: Object: fromAccountData, RLP: fromRlpSerializedAccount, and Array: fromValuesArray.

Methods: isEmpty(): boolean, isContract(): boolean, serialize(): Buffer

Example usage:

import { Account, BN } from 'ethereumjs-util'

const account = new Account(
  new BN(0), // nonce, default: 0
  new BN(10).pow(new BN(18)), // balance, default: 0
  undefined, // stateRoot, default: KECCAK256_RLP (hash of RLP of null)
  undefined, // codeHash, default: KECCAK256_NULL (hash of null)
)

For more info see the documentation, examples of usage in test/account.spec.ts or PR #​275.

New export: TypeScript types

A new file with helpful TypeScript types has been added to the exports of this project, see PR #​275.

In this release it contains BNLike, BufferLike, and TransformableToBuffer.

Address.toBuffer()

The Address class has as a new method address.toBuffer() that will give you a copy of the underlying address.buf (PR #​277).

toBuffer() now converts TransformableToBuffer

The toBuffer() exported function now additionally converts any object with a toBuffer() method (PR #​277).

v7.0.5

Compare Source

This release adds a new module address - see README - with a new Address class and type which can be used for creating and representing Ethereum addresses.

Example usage:

import { Address } from 'ethereumjs-util'

const pubKey = Buffer.from(
  '3a443d8381a6798a70c6ff9304bdc8cb0163c23211d11628fae52ef9e0dca11a001cf066d56a8156fc201cd5df8a36ef694eecd258903fca7086c1fae7441e1d',
  'hex',
)
const address = Address.fromPublicKey(pubKey)

In TypeScript the associated Address type can be used to more strictly enforce type checks (e.g. on the length of an address) on function parameters expecting an address input. So you can declare a function like the following: myAddressRelatedFunction(Address: address) to get more assurance that the address input is correct.

See PR #​186

v7.0.4

Compare Source

• Fixed BN.js and RLP re-export failures from TypeScript, PR #​270
• Fixed an issue along large-value input due to a string copy inconsistency within the assertIs* helper functions, issue affects most methods of the library, PR #​269

v7.0.3

Compare Source

This release replaces the keccak and secp256k1 dependencies (PR #​257) and instead uses the ethereum-cryptography package that uses native JS implementations for cryptographic primitives and makes use of modern and forward-compatible N-API implementations in Node wherever possible.

This is part of a larger initiative led by Nomic Labs to improve the developer experience within the Ethereum developer ecosystem, see ethereum/js-organization#​18 for context.

Other Changes:

• Added TypeScript definitions for ethjs-util methods, PR #​248 and PR #​260

v7.0.2

Compare Source

This patch release re-establishes the state of v7.0.0 release and upgrades the BN.js re-export version back to v5 since quick patches for both the v5 (v5.1.2) and the v4 branch (v4.11.9) have been released to fix interoperability issues between the BN.js versions.

This now makes it possible to move to the latest BN.js v5 version and profit from future upgrades and patches.

An upgrade is highly recommended, the v7.0.1 release will be marked as deprecated along this release.

See: Issue #​250

v7.0.1

Compare Source

[DEPRECATED in favour of v7.0.2]

This patch release downgrades the re-exported BN.js version from v5 to v4 (so a continuation of what has being used within the v6.x versions). This is due to some unexpected interoperability problems in libraries using the older v4 BN.js branch in their some of their respective dependencies.

An upgrade is highly recommended, the v7.0.0 release will be marked as deprecated along this release.

See: Issue #​250

v7.0.0

Compare Source

[DEPRECATED in favour of v7.0.1]

This release comes with significant changes to the API, updated versions of the core crypto libraries and substantial developer improvements in the form of a refactored test suite and API documentation.

API Changes

Changes to the API have been discussed in Issue #​172 and are guided by the principles of:

• Make the API more typestrict
• Be less ambiguous regarding accepted values
• Avoid implicit type conversions
• Be more explicit on wrong input (just: throw)

While the implemented changes come with some additional need for manual type conversions depending on the usage context, they should finally lead to cleaner usage patterns on the cosuming side and a more predictable, robust and less error-prone control flow.

Some note: for methods where Buffer usage is now enforced you can use the Bytes.toBuffer() method for conversion.

Account Module

Enforced Hex Prefixing for Address Strings

PR: #​241

Hex prefixing is now enforced for all address string inputs and functions will throw if a non-hex string is provided:

• Account.isValidAddress()
• Account.isZeroAddress()
• Account.toChecksumAddress()
• Account.isValidChecksumAddress()

The Account.isPrecompile() method was removed from the code base, PR #​242

Enforce Buffer Inputs for Account Methods

PR: #​245

Implicit Buffer conversions for the following methods have been removed and Buffer inputs are now enforced:

• Account.generateAddress()
• Account.generateAddress2()
• Account.pubToAddress()
• AccountprivateToPublic()
• AccountimportPublic()

Bytes Module

Typestrict Methods and Type-Explicit Method Split-Up

PR: #​244

• Enforced Buffer input for Bytes.setLengthLeft(), Bytes.setLengthRight()
• Bytes.setLength() has been removed (alias for Bytes.setLengthLeft())
• Bytes.stripZeros() has been removed (alias for Bytes.unPad())
• Bytes.unpad has been split up into:
  • Bytes.unpadBuffer()
  • Bytes.unpadHexString()
  • Bytes.unpadArray()

Hash Module

Typestrict Methods and Type-Explicit Method Split-Up

PR #​247

The following methods are now Buffer-only:

• Hash.keccak()
• Hash.keccak256()
• Hash.sha256()
• Hash.ripemd160()

Hash.keccak() gets the following additional convenience methods:

• Hash.keccakFromString()
• Hash.keccakFromHexString() (hex string enforced) Hash.keccakFromArray()

Hash.sha256() gets the following additional convenience methods:

• Hash.sha256FromString()
• Hash.sha256FromArray()

Hash.ripemd160() gets the following additional convenience methods:

• Hash.ripemd160FromString()
• Hash.ripemd160FromArray()

Other Breaking Changes

• Added support for Node 14, PR #​249
• Dropped support for Node 8 along PR #​228
• Updated BN.js library re-export from 4.x to 5.x, PR [#​249], #​249
• Removed secp2561 re-export (use methods provided or import directly), PR #​228

Cryto Library Updates: Keccak, secp2561

Keccak dependency has been updated from 2.1.0 to 3.0.0. This version comes with prebuilds for Linux, MacOS and Windows so most users won't need to have node-gyp run on installation.

The version update also brings in feature compatibility with newer Node.js versions.

The secp2561 ECDSA dependency has been updated from 3.0.1 to 4.0.1.

Developer Improvements

• Refactored test suite (module split-up, headless Firefox and Chrome), PR #​231
• Moved CI from Travis to GitHub Actions, PR #​231
• Improved and updated TypeDoc API documentation, PR #​232 and PR #​236
• Basic API tests for re-exports (BN.js, RLP, ethjsUtil), PR #​235

v6.2.1

Compare Source

This release replaces the native secp256k1 and keccak dependencies with ethereum-cryptopgraphy which doesn't need native compilation.
