这里我的代码不接受从
crypto.randomBytes（hash）crypto.randomByteslet hash = crypto.createHash('md5').update(codeToken).digest();
console.log("hash" + hash.toString('hex'));
var initializationVector = crypto.randomBytes(16);
console.log("iv " + initializationVector);
var encrypted = crypto.Cipheriv('aes-128-cbc', hash, initializationVector);
但是，我如何才能像我在步骤中提到的那样传递key和iv呢？我不知道你的算法，所以这里有一个猜测。我尝试了你的代码，但它给了我错误。我已经在我的代码中更新了算法步骤，那么代码是否符合该算法？@Mthaker我修复了代码中的大小问题（十六进制编码的MD5哈希长度为32字节，而不是16字节）。IV必须是不可预测的（读取：随机）。不要使用静态IV或从密钥派生的IV（在本例中是相同的），因为这会使密码具有确定性，因此在语义上不安全。观察密文的攻击者可以确定以前何时发送相同的消息前缀。IV不是秘密，所以你可以把它和密文一起发送。通常，它只是在密文前面加上前缀并在解密之前切掉。“crypto.randomBytes不接受md5生成的utf8字符串”-您认为它为什么应该这样做
