我一直在try 通过AES和C#以可互操作的方式对中的字符串进行加密和解密.我的客户机应用程序是一个 node 服务器,它与dot-NET中供应商的API进行通信.
供应商使用以下方法加密和解密字符串:
public static string Encrypt(string data, string key)
{
string IV = key.Substring(0, 16);
byte[] iv = Encoding.UTF8.GetBytes(IV);
byte[] array;
using(Aes aes = Aes.Create())
{
aes.Key = Encoding.UTF8.GetBytes(key);
aes.IV = iv;
ICryptoTransform encryptor = aes.CreateEncryptor(aes.Key, aes.IV);
using(MemoryStream memoryStream = new MemoryStream())
{
using(CryptoStream cryptoStream = new CryptoStream((Stream)memoryStream, encryptor, CryptoStreamMode.Write))
{
using(StreamWriter streamWriter = new StreamWriter((Stream)cryptoStream))
{
streamWriter.Write(data);
}
array = memoryStream.ToArray();
}
}
}
return Convert.ToBase64String(array);
}
public static string Decrypt(string data, string key)
{
string IV = key.Substring(0, 16);
byte[] iv = Encoding.UTF8.GetBytes(IV);
byte[] buffer = Convert.FromBase64String(data);
using(Aes aes = Aes.Create())
{
aes.Key = Encoding.UTF8.GetBytes(key);
aes.IV = iv;
ICryptoTransform decryptor = aes.CreateDecryptor(aes.Key, aes.IV);
using(MemoryStream memoryStream = new MemoryStream(buffer))
{
using(CryptoStream cryptoStream = new CryptoStream((Stream)memoryStream, decryptor, CryptoStreamMode.Read))
{
using(StreamReader streamReader = new StreamReader((Stream)cryptoStream))
{
return streamReader.ReadToEnd();
}
}
}
}
}
例如,我try 了crypto-js
来解密字符串,但我无法使其工作:
const encryptedText = CryptoJS.enc.Base64.parse(base64Value)
const encrypted2 = encryptedText.toString(CryptoJS.enc.Base64);
const decrypt2 = CryptoJS.AES.decrypt(encrypted2, key, {
mode: CryptoJS.mode.ECB,
padding: CryptoJS.pad.Pkcs7
});
console.log(decrypt2.toString(CryptoJS.enc.Utf8)) // (also tried various other encodings, Utf16, Utf16LE and others)
