javascript - 解密 RSA 数据时出现 DOMException

Question

我正在尝试将加密数据从服务器发送到客户端，并使用window.crypto.subtle.decrypt()对其进行解密。但我有一个没有描述的错误。我该如何修复它？

node.js 服务器代码:

const sharedKey = (req, res, next) => {
  let crypto = require('crypto');

  let buf = Buffer.from('Hello, my friend');

  const key = {
    key: req.body.public,
    padding: crypto.constants.RSA_PKCS1_OAEP_PADDING
  }

  try {
    let encrypted = crypto.publicEncrypt(key, buf);
    res.send(encrypted.toString('base64'));
  } catch (err) {
    console.log('err', err)
  }
};

客户端代码:

$.post('/register', {
  'login': login,
  'public': publicKeyPEM
}, function(data) {
  console.log('data', data);
  data = Ocrypto.base64ToArrayBuffer(data);
  try {
    window.crypto.subtle.decrypt({
          name: "RSA-OAEP",
          //label: Uint8Array([...]) //optional
        },
        keyPair.privateKey, //from generateKey or importKey above
        data //ArrayBuffer of the data
      )
      .then(function(decrypted) {
        //returns an ArrayBuffer containing the decrypted data
        console.log(new Uint8Array(decrypted));
      })
      .catch(function(err) {
        console.log("ERRRRRR", err);
      });
  } catch (error) {
    console.log('err', err)

  }
});

我在控制台中得到的内容:“ERRRRRRR DOMException”

Answer 1

data = Ocrypto.base64ToArrayBuffer(data);

您似乎有一个拼写错误。
