openpgp.decrypt 在 jest 上运行时返回空字符串

如何解决openpgp.decrypt 在 jest 上运行时返回空字符串

我有以下功能，我使用的是 TypeScript 和 OpenPGP JS 库

import * as openpgp from "openpgp";

export async function decryptMessage(
  privateKeyArmored: string,passphrase: string,encrypted: string
) {
  const {
    keys: [privateKey]
  } = await openpgp.key.readArmored(privateKeyArmored);

  await privateKey.decrypt(passphrase);

  const { data: decrypted } = await openpgp.decrypt({
    message: await openpgp.message.readArmored(encrypted),privateKeys: [privateKey]
  });

  return decrypted;
}

还有我的单元测试：

import * as openpgp from "openpgp";

import { decryptMessage } from "../src/crypto";

const oldTextEncoder = global.TextEncoder;
const oldTextDecoder = global.TextDecoder;

describe("crypto",() => {
  const passphrase = "test";
  let privateKey: string;
  let publicKey: string;

  beforeAll(async () => {
    const textEncoding = await import("text-encoding-utf-8");
    global.TextEncoder = textEncoding.TextEncoder;
    global.TextDecoder = textEncoding.TextDecoder;

    const { privateKeyArmored,publicKeyArmored } = await openpgp.generateKey({
      userIds: [{ name: "username" }],curve: "ed25519",passphrase
    });

    privateKey = privateKeyArmored;
    publicKey = publicKeyArmored;
  });

  afterall(() => {
    global.TextEncoder = oldTextEncoder;
    global.TextDecoder = oldTextDecoder;
  });

  test("decrypt message",async () => {
    const text = "test"

    const { data: encrypted } = await openpgp.encrypt({
      message: openpgp.message.fromText(text),publicKeys: (await openpgp.key.readArmored(publicKey)).keys,});

    const result = await decryptMessage(privateKey,passphrase,encrypted);

    expect(result).toBe(text);
  });
});

在行 expect(result).toBe(text); 我收到一个空字符串并且我的测试失败

expect(received).toBe(expected) // Object.is equality

Expected: "test"
Received: ""

该函数在生产环境中有效，但在 jest 下运行没有警告，只返回一个空字符串。

如果我更改密码，我得到了一个异常，所以代码没问题，jest 环境下有什么东西。

我错过了什么吗？
