在C# Winform中处理数据报表数据加密解密,可以使用对称加密算法(如AES)或非对称加密算法(如RSA)。这里以AES加密解密为例,介绍如何在Winform应用中实现数据的加密和解密。
using System;
using System.IO;
using System.Security.Cryptography;
using System.Text;
public static class EncryptDecryptHelper
{
private static readonly byte[] Key = Encoding.UTF8.GetBytes("your_key_here"); // 替换为你的密钥
private static readonly byte[] IV = Encoding.UTF8.GetBytes("your_iv_here"); // 替换为你的初始向量
public static string Encrypt(string plainText)
{
using (Aes aes = Aes.Create())
{
aes.Key = Key;
aes.IV = IV;
ICryptoTransform encryptor = aes.CreateEncryptor(aes.Key, aes.IV);
using (MemoryStream ms = new MemoryStream())
{
using (CryptoStream cs = new CryptoStream(ms, encryptor, CryptoStreamMode.Write))
{
using (StreamWriter sw = new StreamWriter(cs))
{
sw.Write(plainText);
}
}
return Convert.ToBase64String(ms.ToArray());
}
}
}
public static string Decrypt(string cipherText)
{
using (Aes aes = Aes.Create())
{
aes.Key = Key;
aes.IV = IV;
ICryptoTransform decryptor = aes.CreateDecryptor(aes.Key, aes.IV);
using (MemoryStream ms = new MemoryStream(Convert.FromBase64String(cipherText)))
{
using (CryptoStream cs = new CryptoStream(ms, decryptor, CryptoStreamMode.Read))
{
using (StreamReader sr = new StreamReader(cs))
{
return sr.ReadToEnd();
}
}
}
}
}
}
private void buttonEncrypt_Click(object sender, EventArgs e)
{
string plainText = textBoxPlainText.Text;
string encryptedText = EncryptDecryptHelper.Encrypt(plainText);
MessageBox.Show("加密后的文本: " + encryptedText);
}
private void buttonDecrypt_Click(object sender, EventArgs e)
{
string encryptedText = textBoxEncryptedText.Text;
string decryptedText = EncryptDecryptHelper.Decrypt(encryptedText);
MessageBox.Show("解密后的文本: " + decryptedText);
}
这样,你就可以在C# Winform应用中对数据报表数据进行加密和解密了。请确保将your_key_here
和your_iv_here
替换为你自己的密钥和初始向量。为了保证数据安全,建议将密钥和初始向量存储在安全的地方,而不是直接写在代码中。
