通过 powershell 和 sharepoint 应用程序页面调用以下加密和解密算法:
public static string Encrypt(string dataToEncrypt, string password, string salt)
{
AesManaged aes = null;
MemoryStream memoryStream = null;
CryptoStream cryptoStream = null;
try
{
Rfc2898DeriveBytes rfc2898 = new Rfc2898DeriveBytes(password, Encoding.UTF8.GetBytes(salt), 10000);
aes = new AesManaged();
aes.Key = rfc2898.GetBytes(32);
aes.IV = rfc2898.GetBytes(16);
memoryStream = new MemoryStream();
cryptoStream = new CryptoStream(memoryStream, aes.CreateEncryptor(), CryptoStreamMode.Write);
byte[] data = Encoding.UTF8.GetBytes(dataToEncrypt);
cryptoStream.Write(data, 0, data.Length);
cryptoStream.FlushFinalBlock();
return Convert.ToBase64String(memoryStream.ToArray());
}
finally
{
if (cryptoStream != null)
cryptoStream.Close();
if (memoryStream != null)
memoryStream.Close();
if (aes != null)
aes.Clear();
}
}
为什么加密的字符串会发生变化?是关于应用领域的吗?
