EthereumはKeccak-256を使用し、Nodeのcrypto.createHash('sha3-256')が公開するNIST標準化SHA3バリアントではない。 Ethereum関数セレクターやイベントトピックの計算 JS/TSでEIP-712、署名、Merkle、またはストレージスロットヘルパーの構築 Nodeのcryptoを直接使用してEthereumデータをハッシュするコードのレビュー 2つのアルゴリズムは同じ入力に対して異なる出力を生成し、Nodeは警告しない。 Ethereumコンテキストでは、crypto.createHash('sha3-256')を絶対に使用しない。ethers、viem、web3、または別の明示的なKeccak実装のKeccak対応ヘルパーを使用すること。
