如何完全序列化/反序列化RSAParameters對象

Question

RSAParameters對象不支持序列化私鑰數據。我如何完全序列化和反序列化私鑰？

Answer 1

使用您自己選擇的序列化程序，可以使用以下代碼來序列化和反序列化RSAParameters對象。

using System; 
using System.Runtime.Serialization; 
using System.Security.Cryptography; 

[Serializable] 
public class RSAParametersSerializable : ISerializable 
{ 
    private RSAParameters _rsaParameters; 

    public RSAParameters RSAParameters 
    { 
     get 
     { 
      return _rsaParameters; 
     } 
    } 

    public RSAParametersSerializable(RSAParameters rsaParameters) 
    { 
     _rsaParameters = rsaParameters; 
    } 

    private RSAParametersSerializable() 
    { 
    } 

    public byte[] D { get { return _rsaParameters.D; } set { _rsaParameters.D = value; } } 

    public byte[] DP { get { return _rsaParameters.DP; } set { _rsaParameters.DP = value; } } 

    public byte[] DQ { get { return _rsaParameters.DQ; } set { _rsaParameters.DQ = value; } } 

    public byte[] Exponent { get { return _rsaParameters.Exponent; } set { _rsaParameters.Exponent = value; } } 

    public byte[] InverseQ { get { return _rsaParameters.InverseQ; } set { _rsaParameters.InverseQ = value; } } 

    public byte[] Modulus { get { return _rsaParameters.Modulus; } set { _rsaParameters.Modulus = value; } } 

    public byte[] P { get { return _rsaParameters.P; } set { _rsaParameters.P = value; } } 

    public byte[] Q { get { return _rsaParameters.Q; } set { _rsaParameters.Q = value; } } 

    public RSAParametersSerializable(SerializationInfo information, StreamingContext context) 
    { 
     _rsaParameters = new RSAParameters() 
     { 
      D = (byte[])information.GetValue("D", typeof(byte[])), 
      DP = (byte[])information.GetValue("DP", typeof(byte[])), 
      DQ = (byte[])information.GetValue("DQ", typeof(byte[])), 
      Exponent = (byte[])information.GetValue("Exponent", typeof(byte[])), 
      InverseQ = (byte[])information.GetValue("InverseQ", typeof(byte[])), 
      Modulus = (byte[])information.GetValue("Modulus", typeof(byte[])), 
      P = (byte[])information.GetValue("P", typeof(byte[])), 
      Q = (byte[])information.GetValue("Q", typeof(byte[])) 
     }; 
    } 

    public void GetObjectData(SerializationInfo info, StreamingContext context) 
    { 
     info.AddValue("D", _rsaParameters.D); 
     info.AddValue("DP", _rsaParameters.DP); 
     info.AddValue("DQ", _rsaParameters.DQ); 
     info.AddValue("Exponent", _rsaParameters.Exponent); 
     info.AddValue("InverseQ", _rsaParameters.InverseQ); 
     info.AddValue("Modulus", _rsaParameters.Modulus); 
     info.AddValue("P", _rsaParameters.P); 
     info.AddValue("Q", _rsaParameters.Q); 
    } 
}
