- `@polkadot/wasm-crypto` 3.1.1


## 5.0.1 Dec 13, 2020

**Important** While this package contains no external interface changes, it now compiles and ships both cjs and esm modules. This means that modern bundlers will have more information for tree-shaking available. Additionally when using Node with `.mjs` extensions, the esm version imports will be used on recent Node versions. Adding an export map, as here, may have some impacts so a major semver bump is advised. There may be (small) dragons hiding in the dark corners...

Changes:

- Build and expose both cjs and esm via exports map
- Use `import type { ... }` form for all type imports
- Align with Substrate master network list
- Debug logs now don't depend on `NODE_ENV`, but rather `DEBUG=<type,type,...>` (`*` logs all)

## 4.0.1 Nov 8, 2020

Changes:

- Remove built-in utility polyfills for `Array.fill`, `String.padStart`, `String.padEnd` as well as `Object.setPrototypeOf`. These should be provided by the actual user of the libraries if so required.
- Update `@polkadot/wasm-crypto` library (under-the-hood cleanups)
- Remove explicit crypto polyfill injection (aligning with updated `@polkadot/wasm-crypto`)
- Add cross-environment `@polkadot/x-randomvalues` (for use in `@polkadot/wasm-crypto`)

- Misc. CI infrastructure cleanups


## 2.6.1 Feb 29, 2020

- **Breaking change** Following on the 2.0 release, `@polkadot/wasm` was updated to 1.1+. sr25510 now only verifies 0.8+ signatures, closing the loop on dropping Substrate 1.x-era support

Changes:

- Add `signatureVerify (message: Uint8Array | string, signature: Uint8Array | string, addressOrPublicKey: Uint8Array | string): VerifyResult` to verify any signature, regardless of type. Returns validity & detected crypto type.
- Add `cryptoIsReady (): boolean` function to check status of initialization

## 2.4.1 Feb 18, 2020

Changes:

- Ensure that `formatBalance` does not apply unit overrides apply when no SI is applicable
- Adjust `formatBalance(<balance>, <options>)` to take expanded `withUnit: string | boolean` option where string is an actual unit, e.g. `KSM`
- The `decimals` option to `formatBalance` should now be passed as part of the `options` (previous last-param deprecated)
- The `.setSS58Format` on keyring will now just operate on pairs created on the keyring, not globally. The global `setSS58Format` in `@polkadot/util-crypto` will be deprecated.
- The deprecated `addressPrefix` option to keyring has been belatedly removed (Use `ss58Format` rather)


## 2.3.1 Feb 15, 2020

Contributed:

- Remove dependency on moment.js with `formatDate` function (Thanks to https://github.com/AndreasGassmann)
- Move TypeScript `@types/*` to dev deps (Thanks to https://github.com/AndreasGassmann)

## 1.6.1 Oct 24, 2019

Changes:

- `pair.sign(message)` now takes an optional second `options?: SignOptions` parameter, where `SignOptions` is currently defined as `{ withType: boolean }`. Here `withType` instructs the signing to prepend the type of signature (ed2551, sr25519 or ecdsa). This is used for the new Polkadot/Substrate MultiSignature format.


## 1.5.1 Sep 25, 2019

Changes:

- Fix typings on the Keyring-exposed encode & decodeAddress
- Allow ss58Format = 0 as a valid value

- Swap to [Babel 7.6.0](https://babeljs.io/) for all compilation, for latest improvements in code generation


## 1.3.1 Sep 10, 2019

Changes:

- Remove the `ExtError` class, always prefer the standard JS `Error` object for errors. This would bre a breaking change for any applications using `ExtError`


## 1.2.1 Sep 09, 2019

Changes:

- Keyring `addFromAddress` can now be used to store external accounts, for example those provided by external signers
- Maintainability updates


## 1.1.1 Aug 09, 2019

Changes:

- `assertSingletonPackage` now warns via console.warn, but does not throw. This does allow the info to come accross while still allowing the app developers using multiple libraries time to fix.

Changes:

- `formatBalance` now allows for `Compact` inputs
- `formaBalance` now allows correct formatting of very large decimals


## 0.94.1 Jul 20, 2019
Changes:

- Add `checkAddress(address, prefix)` to `@polkadot/util-crypto` that validates an ss-58 address
- Add support for the Kusama network (as a valid checked prefix)
- Add an `asm.js` fallback for the React Native environment (via `@polkadot/wasm-crypto`)
- The ed25519 key for Alice (representing the session), now appears in the test keyrings
- Fix missing dependencies for keyring (after address moves in 0.93.1)


## 0.93.1 Jun 14, 2019

Changes:

- Breaking: External pair interface for keyring has been changed. Instead of
  - `getMeta` use the `meta` getter, i.e. `console.log(pair.meta.name)`
  - `address` use the `address` getter, i.e. `console.log(pair.address)`
  - `publicKey` use the `publicKey` getter, i.e. `console.log(pair.publicKey)`
- `Move decodeAddress`, `encodeAddress` & `setAddressPrefix` functions into `@polkadot/util-crypto` from `@polkadot/keyring`. External interfaces should not be affected at this point since it is also (still) exported and exposed on keyring


## 0.92.1 Jun 04, 2019

Changes:

- Only allow integer input values into `formatBalance`
- Allow `formatBalance`, `formatDecimal` & `formatNumber` to cater for negative numbers
- Add 'Bob//stash' to testing keyring, joining the existing 'Alice//stash'


## 0.91.1 May 22, 2019

Changes:

- ed25519/sr25519 sign & verify functions can now take the message input as Uint8Array/string/hex and verify allows for the signature/publicKey to be specified as Uint8Array/hex
- Update `@polkadot/wasm` to include a maintenance bump for the `w3f/schnorrkel` libraries


## 0.90.1 May 08, 2019

Changes:

- Moving towards 1.0
- Added bnMin & bnMax functions


## 0.76.1 Apr 03, 2019

Changes:

- Fix `addFromMnemonic` to generate using new-style derivation.
- Pull in `formatBalance`, `formatDecimal`, `formatElapsed`, `formatNumber`, `calcSi`, `findSi` & `isTestChain` utility functions from the originals in `@polkadot/ui-util`
- Swap out `wasm-schnorrkel` & `wasm-ed25519` for combined version with `wasm-crypto`
- Swap DB interfaces to optional LRU, removing `transactionAsync` (client-only changes)


## 0.75.1 Mar 29, 2019

Changes:

- Start journey to 1.0


## 0.42.1 Mar 28, 2019

Changes:

- Add `assertSingletonPackage` to util
- Ensure that only a single keyring instance is loaded (uses above)


## 0.41.1 Mar 25, 2019

Changes:

- Extensions to the client-specific database interfaces (non-breaking for API and util users)


## 0.40.1 Mar 23, 2019

Changes:

- Add additional derivation path extraction mechanisms to util-crypto
- Add createFromUri function to keypair (creates keypair, does not add it)
- Allow all crypto hashing & ed25519 to use WASM (as available, JS fallbacks)


## 0.39.1 Mar 20, 2019

Changes:

- Pull in bip39 generation functions from `@poladkot/wasm-crypto` with a fallback to the pure JS versions


## 0.38.1 Mar 18, 2019

Changes:

- Align with current substrate master for sr25519 keys and hard/soft derivation
- Swap default dev keys to derived (sr25519)


## 0.37.1 Mar 14, 2019

Changes:

- Swap to publishing -beta.x on merge (non-breaking testing)


## 0.36.1 Mar 13, 2019

Changes:

- Add `fromUri` to keyring along with hard & soft key derivation.


## 0.35.1 Mar 04, 2019

Changes:

- Remove NodeJs-only `syncify` function, not exported by the package (with binary dependency for Node)


## 0.34.1 Feb 13, 2019

Changes:

- Keyring now allows for ed25519 and sr25519 instances. Upon creation, you need to pass the `ed25519`or `sr25519` string to denote the type, i.e. `new Keyring({ type: 'sr25519' })`
