nodejs-keccak256
Prevents Ethereum hashing errors in JavaScript and TypeScript. Node's sha3-256 is NIST SHA3, not Ethereum Keccak-256, and silently breaks selectors, signatures, storage slots, and address derivation.

以太坊使用 Keccak-256，而非 Node 的 crypto.createHash('sha3-256') 所暴露的 NIST 标准化 SHA3 变体。 计算以太坊函数选择器或事件主题 在 JS/TS 中构建 EIP-712、签名、Merkle 或存储槽辅助函数 审查任何直接使用 Node crypto 对以太坊数据进行哈希的代码 两种算法对相同输入会产生不同输出，且 Node 不会发出警告。 在以太坊上下文中，切勿使用 crypto.createHash('sha3-256')。应使用来自 ethers、viem、web3 或其他明确 Keccak 实现的 Keccak 感知辅助函数。
