v4.0.1

• Breaking change Polyfills are not injected by these libraries anymore to avoid clobbering external globals, the user should provide them if their environment is missing base functionality.

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)

v3.7.1

Changes:

• Remove the use of chalk (logger) for less overall dependencies
• string* utilities now also allows String (class) inputs
• Align bip39 use with wasm-crypto for English-only wordlist, default, non supplied)
• Adjust elliptic imports for explicit paths (allows tree-shaking)
• Add Totem (ss58 prefix 14) into @polkadot/networks
• Move @polkadot/x-{fetch,textdecoder,textencoder,ws} into common repo

v3.6.1

Contributed:

• Add evmToAddress and addressToEvm @polkadot/util-crypto (Thanks to https://github.com/jnaviask)
• Remove invalid link to docs (thanks to https://github.com/roccomuso)

Changes:

• Rename mnemonicToBip39 to mnemonicToLegacySeed (used in non-Substrate compatible fashion)
• Update pair signature verification to handle MultiSignature results
• Move documentation to docs repo
• Added @polkadot/networks for a list of known networks and their identifying information

v3.5.1

Contributed:

• Add Dock network identifiers (Thanks to https://github.com/lovesh)

Changes:

• Use cross-environment TextDecoder & TextEncoder from the polkadot-js polyfills
• Add isBase{32, 58, 64} to @polkadot/util-crypto
• Add base64{Pad, Trim} to add/remove padding characters
• Add createFromJson(json) to keyring (create pair without adding)
• Balance formatter now outputs 4 numbers after the decimal point

v3.4.1

• Allow for WASM-as-available mnemonicToBip39 call (used for Ethereum-compatible keypairs)
• Add isWasm utility to check for valid WASM headers
• @polkadot/wasm-crypto 1.4.1

v3.3.1

• Add addressRaw to Keyring interface (if address encoding is different to publicKey)
• Allow for Ethereum pair signing and verification

v3.2.1

• Allow for (optional, default blake2) hasher to secp256k1 sign/verify functions
• Utilities for secp256k1 publicKey expansion and compression
• Add basic Ethereum address utils (encode with checksum & checksum verification)
• Add Ethereum-compatible mnemonicToBip39 seed creation function

v3.1.1

• Add deriveAddress(<address>, '/<soft>/<soft-b>') via sr25519 soft
• Use scrypt from WASM as available (JS fallback in place)
• Add base32{Encode, Decode} utilities (IPFS-compatible alphabet)
• Support IPFS compatibility flag in base58 encoding/decoding
• Update to @polkadot/wasm-crypto 1.3.1

v3.0.1

• Add Katal ss58Format (Thanks to https://github.com/retotrinkler)
• Adjust JSON pair output with scrypt kdf (version 3 output)

v2.18.1

• Add base64{Decode, Encode, Validate} as crypto utils
• Extract base58Validate from base58 decode checks
• Add isAscii to allow detection of printable ASCII sequences (including tab, newline)
• Add isUtf8 to allow detection of valid Utf8 sequences
