BLS HD 密钥公用事业

用于管理 BLS 继承式决定性账户的功能 .

1. 从 Entropy 创建主密钥
2. 从私钥和索引创建儿童私钥
3. 将标准路径转换成一系列索引
4. 从私人密钥和一系列指数中创建一个失真私钥

执行方式如下: EIP-2334, (中文(简体) ), EIP-2333

关于更高层次的界面,参见 @ 链条安全/ bls- keygen。 。 。 .

示例

import {deriveMasterSK, deriveChildSK, deriveChildSKMultiple, pathToIndices} from "@chainsafe/bls-hd-key";

// Create master private key (according to EIP-2333)

const entropy: Uint8Array = Uint8Array.from(...);
const masterKey: Uint8Array = deriveMasterSK(entropy);

// Create child private key one level deep

const childIndex: number = ...;
const childKey: Uint8Array = deriveChildSK(masterKey, childIndex);

// Convert a "path" into an array of indices (using validation rules of EIP-2334)

cont path = "m/12381/3600/0/0";
const childIndices: number[] = pathToIndices(path);

// Convert a "path" into an array of indices (validating an alternate key type)

const eth1KeyType = 60;
cont path = "m/12381/60/0/0";
const childIndices: number[] = pathToIndices(path, eth1KeyType);

// Create a child private key `childIndices.length` levels deep

const childIndices: number[] = [...];
const childKey = deriveChildSKMultiple(masterKey, childIndices);

// Compose functions to derive a child key from entropy and a path

const entropy: Uint8Array = Uint8Array.from(...);
cont path = "m/12381/3600/0/0";
const childKey = deriveChildSKMultiple(deriveMasterSK(entropy), pathToIndices(path));
