C#实现文件加密与解密
代码：
static class HandleFiles
{
public static void EncryptFile(string inputFile, string outputFile) //加密
{
try
{
string password = @"12345678";
UnicodeEncoding UE = new UnicodeEncoding();
byte[] key = UE.GetBytes(password);
string cryptFile = outputFile;
FileStream fsCrypt = new FileStream(cryptFile, FileMode.Create);
RijndaelManaged RMCrypto = new RijndaelManaged();
CryptoStream cs = new CryptoStream(fsCrypt,
RMCrypto.CreateEncryptor(key, key),
CryptoStreamMode.Write);
FileStream fsIn = new FileStream(inputFile, FileMode.Open);
int data;
while ((data = fsIn.ReadByte()) != -1)
cs.WriteByte((byte)data);
fsIn.Close();
cs.Close();
fsCrypt.Close();
MessageBox.Show("Encrypt Source file succeed!", "Msg :");
}
catch(Exception ex)
{
MessageBox.Show("Source file error!", "Error :");
}
}
public static void DecryptFile(string inputFile, string outputFile) //解密
{
try
{
string password = @"12345678";
UnicodeEncoding UE = new UnicodeEncoding();
byte[] key = UE.GetBytes(password);
FileStream fsCrypt = new FileStream(inputFile, FileMode.Open);
RijndaelManaged RMCrypto = new RijndaelManaged();
CryptoStream cs = new CryptoStream(fsCrypt,
RMCrypto.CreateDecryptor(key, key),
CryptoStreamMode.Read);
FileStream fsOut = new FileStream(outputFile, FileMode.Create);
int data;
while ((data = cs.ReadByte()) != -1)
fsOut.WriteByte((byte)data);
fsOut.Close();
cs.Close();
fsCrypt.Close();
MessageBox.Show("Decrypt Source file succeed!", "Msg :");
}
catch(Exception ex)
{
MessageBox.Show("Source file error", "Error :");
}
}
}
C#进行url加密解密与jquery前端加密解密
当我们程序发布于服务器上会遇到前端报错。因为有特殊原因导致。
此时需要对传输的数据，进行加密，后台进行解密处理
C#进行url加密与解密
HttpUtility.UrlEncode(val); //utf-8 编码
HttpUtility.UrlDecode(val); //utf-8 解码
HttpUtility.UrlEncode(val, System.Text.Encoding.GetEncoding(936)); //gb2312编码
HttpUtility.UrlDecode(val, System.Text.Encoding.GetEncoding(936)); //gb2312解码
System.Web.HttpUtility.UrlEncode(val, System.Text.Encoding.GetEncoding("GB2312"));//gb2312编码
System.Web.HttpUtility.UrlDecode(val, System.Text.Encoding.GetEncoding("GB2312"));//gb2312解码jquery
decodeURIComponent(val);//Jquery解码 encodeURIComponent(val);//Jquery编码
总结
以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
