【问题描述】：

我使用 Openpgp.js 生成了密钥，并将以下密钥作为公钥：

publicKey: "-----BEGIN PGP PUBLIC KEY BLOCK-----\n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\nqYlNhcVH5aw1CQ==\n=G/+7\n-----END PGP PUBLIC KEY BLOCK-----\n"

现在我尝试运行以下 js 代码以加密消息：

async function EncryptMessage(pubkey, msg) {
  var openpgp = window.openpgp;
  var public_key = pubkey.value;
  console.log(public_key);
  var message = msg.value;
  console.log("message: " + message);
  const email = {
    subject: "Message",
    body: message
  }
  console.log(email)
  const options = {
      data: JSON.stringify(email),
      publicKeyArmored: public_key
  };
  console.log(options)
  let messageForOp = "";
  openpgp.encrypt(options)
      .then((cipherText)=>{
           messageForOp = cipherText.data;
           console.log(messageForOp)
      });
}

我的控制台正在记录这个：

"-----BEGIN PGP PUBLIC KEY BLOCK-----\n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\nqYlNhcVH5aw1CQ==\n=G/+7\n-----END PGP PUBLIC KEY BLOCK-----\n"

message: hello world 

Object { subject: "Message", body: "hello world" }

错误得到：

Uncaught (in promise) Error: Parameter [message] needs to be of type Message   openpgp.js:619:14

【解决方案1】：

我认为您在那里看到的是您没有创建消息，并且 encrypt 方法需要一个具有Message 类型的消息属性的对象。

const email = {
  subject: 'Message',
  body: message,
}

const message = await createMessage({ text: JSON.stringify(email), format: 'text' })

await encrypt({
  message,
  encryptionKeys: public_key,
})
