好吧,我知道它可能在 Stackoverflow 上不受欢迎,it is not a code-writing service
但我发现这个挑战是一项很好的运动,所以这里是:
let clearText = '123456';
let encryptionKey = CryptoJS.enc.Utf8.parse('secret key string');
let salt = CryptoJS.enc.Base64.parse('SXZhbiBNZWR2ZWRldg=='); // this is the byte array in .net fiddle
let iterations = 1000; // https://docs.microsoft.com/en-us/dotnet/api/system.security.cryptography.rfc2898derivebytes?view=netcore-3.1
let keyAndIv = CryptoJS.PBKDF2(encryptionKey, salt, { keySize: 256/32 + 128/32, iterations: iterations, hasher: CryptoJS.algo.SHA1 }); // so PBKDF2 in CryptoJS is direct in that it
// always begins at the beginning of the password, whereas the .net
// implementation offsets by the last length each time .GetBytes() is called
// so we had to generate a Iv + Salt password and then split it
let hexKeyAndIv = CryptoJS.enc.Hex.stringify(keyAndIv);
let key = CryptoJS.enc.Hex.parse(hexKeyAndIv.substring(0, 64));
let iv = CryptoJS.enc.Hex.parse(hexKeyAndIv.substring(64, hexKeyAndIv.length));
// As you're using Encoding.Unicde in .net, we have to use CryptoJS.enc.Utf16LE here.
let encryptedStr = CryptoJS.AES.encrypt(CryptoJS.enc.Utf16LE.parse(clearText), key, {iv: iv}).toString();
console.log(encryptedStr)

这是我在 .Net fiddle 中使用的相应代码(遗憾的是,它不允许在不登录的情况下“保存”),我使用了 .Net Core 3.1 运行时和System.Security.Cryptography.Algorithms
nuget 包。
using System;
using System.IO;
using System.Text;
using System.Security.Cryptography;
public class Program
{
public static void Main()
{
var clearText = "123456";
var EncryptionKey = "secret key string";
var clearBytes = Encoding.Unicode.GetBytes(clearText);
using (System.Security.Cryptography.Aes encryptor = Aes.Create())
{
Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(EncryptionKey, new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 });
encryptor.Key = pdb.GetBytes(32);
encryptor.IV = pdb.GetBytes(16);
using (MemoryStream ms = new MemoryStream())
{
using (CryptoStream cs = new CryptoStream(ms, encryptor.CreateEncryptor(), CryptoStreamMode.Write))
{
cs.Write(clearBytes, 0, clearBytes.Length);
cs.Close();
}
clearText = Convert.ToBase64String(ms.ToArray());
}
}
Console.WriteLine(clearText);
}
}
两个列表都打印相同的字符串。
正如评论中提到的,最大的挑战是,由于您的 .Net 代码重复使用相同的 PBKDF2 实例,因此每次.GetBytes()
调用本质上cb
都是密码的下一个。(cb 是 .net 代码中的参数名称https://docs.microsoft.com/en-us/dotnet/api/system.security.cryptography.rfc2898derivebytes.getbytes?view=netcore-3.1#System_Security_Cryptography_Rfc2898DeriveBytes_GetBytes_System_Int32_)
CryptoJS 中的 PBKDF2 没有这个,所以我们需要调用它一次并获取 Key 和 Iv,然后自己进行解析。
