[Dev] ハッシュ計算いろいろ

■方法1：Node.js 標準 crypto
import { createHash } from "crypto";
function sha256(data: Uint8Array): Uint8Array { return new Uint8Array(createHash("sha256").update(data).digest()); }
const digest = sha256(new TextEncoder().encode(message));

■方法2：dsteem の cryptoUtils.sha256
import dsteem from 'dsteem';
const digest2 = dsteem.cryptoUtils.sha256(Buffer.from(message, "utf8"));

■方法3：Bun 独自 Bun.SHA256.hash
const digest3 = Bun.SHA256.hash(new TextEncoder().encode(message));

■バッファ、Uint8Array変換
const uint8 = new Uint8Array(digest2);

■Uint8Array同士の比較
const isEqual = (a: Uint8Array, b: Uint8Array) => a.length === b.length && a.every((v, i) => v === b[i]);
console.log(isEqual(digest, digest2));
