我是密码学的新手。
已编辑:使用正确的加密/解密算法似乎错了,所以我将问题更改为:
如何将这些代码行转换为WinRT?
代码基于http://msdn.microsoft.com/en-us/library/system.security.cryptography.aesmanaged.aspx
处的代码我需要在WinRT中做同样的事情:
更新
WinRT(Windows 8.1)的密码学和证书样本解决了我的问题。
请检查:http://code.msdn.microsoft.com/windowsapps/Cryptography-and-3305467b
public static byte[] Encrypt(string plainText)
{
if (plainText == null || plainText.Length <= 0)
throw new ArgumentNullException("plainText");
if (Key == null || Key.Length <= 0)
throw new ArgumentNullException("Key");
if (IV == null || IV.Length <= 0)
throw new ArgumentNullException("Key");
byte[] encrypted;
using (AesManaged aesAlg = new AesManaged())
{
aesAlg.Key = Key;
aesAlg.IV = IV;
// Create a decrytor to perform the stream transform.
ICryptoTransform encryptor = aesAlg.CreateEncryptor(aesAlg.Key, aesAlg.IV);
using (MemoryStream msEncrypt = new MemoryStream())
{
using (CryptoStream csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write))
{
using (StreamWriter swEncrypt = new StreamWriter(csEncrypt))
{
//Write all data to the stream.
swEncrypt.Write(plainText);
}
encrypted = msEncrypt.ToArray();
}
}
}
return encrypted;
}
和
public static string Decrypt(byte[] cipherText)
{
if (cipherText == null || cipherText.Length <= 0)
throw new ArgumentNullException("cipherText");
if (Key == null || Key.Length <= 0)
throw new ArgumentNullException("Key");
if (IV == null || IV.Length <= 0)
throw new ArgumentNullException("Key");
string plaintext = null;
using (AesManaged aesAlg = new AesManaged())
{
aesAlg.Key = Key;
aesAlg.IV = IV;
// Create a decrytor to perform the stream transform.
ICryptoTransform decryptor = aesAlg.CreateDecryptor(aesAlg.Key, aesAlg.IV);
using (MemoryStream msDecrypt = new MemoryStream(cipherText))
{
using (CryptoStream csDecrypt = new CryptoStream(msDecrypt, decryptor, CryptoStreamMode.Read))
{
using (StreamReader srDecrypt = new StreamReader(csDecrypt))
{
// Read the decrypted bytes from the decrypting stream // and place them in a string.
plaintext = srDecrypt.ReadToEnd();
}
}
}
}
return plaintext;
}
答案 0 :(得分:0)
是的,这是可能的,但你应该使用相同的:
当然还有正确的密码(AES代替Rijndael),对称密钥大小和值以及IV。确保分别检查这些功能的每个IO 。不要依赖默认值,明确设置每个值。
请注意,使用ECB模式是不安全的。目前你可能正在混合CBC和ECB模式,这是行不通的。要进行安全通信,您应使用authenticated encryption或MAC(使用第二个密钥)。
