7.0.5 - 2020-09-09
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
7.0.4 - 2020-08-04
- Fixed
BN.js
andRLP
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
7.0.3 - 2020-07-07
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-team-organization#18 for context.

7.0.2 - 2020-05-25
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
7.0.1 - 2020-05-15
[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
7.0.0 - 2020-04-30
[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.
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.
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
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()
PR: #244

input forBytes.setLengthLeft()

)Bytes.stripZeros()

The following methods are now Buffer
-only:

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
.

- Improved and updated

6.2.0 - 2019-11-06
This release comes with a new file structure, related functionality is now broken
down into separate files (like account.js
) allowing for more oversight and
modular integration. All functionality is additionally exposed through an
aggregating index.js
file, so this version remains backwards-compatible.
Overview on the new structure:
account
: Private/public key and address-related functionality (creation, validation, conversion)byte
: Byte-related helper and conversion functionsconstants
: Exposed constants (e.g.KECCAK256_NULL_S
for the string representation of the Keccak-256 hash of null)hash
: Hash functionsobject
: Helper function for creating a binary object (DEPRECATED
)signature
: Signing, signature validation, conversion, recovery
See associated PRs #182 and #179.
