测试个加密文件!
namespace EncriptStringTest {
class Program {
static void Main (string[] args) {
Console.WriteLine("Input The String to to Encrypt:");
string strToEn = Console.ReadLine(); //待加密的字符串.
string strEnResult = EncriptHelper.Encript(strToEn); //调用方法,加密字符串.
Console.WriteLine("加密后的字符串为:\n" + strEnResult);
Console.ReadKey();
}
}
//加密类.
class EncriptHelper {
public static string enKey = "theKey"; //密匙.
public static string Encript (string strToEn) {
DESCryptoServiceProvider descrypt = new DESCryptoServiceProvider(); //加密字符串.
byte[] keys = Encoding.Unicode.GetBytes(enKey);
byte[] values = Encoding.Unicode.GetBytes(strToEn);
MemoryStream mStream = new MemoryStream(); //内存流.
//通过"内存流"创建贾米流对象.
CryptoStream cStream = new CryptoStream(mStream, descrypt.CreateEncryptor(keys,values), CryptoStreamMode.Write);
cStream.Write(values, 0, values.Length); //写入内存.
cStream.FlushFinalBlock(); //刷新写入的加密字符串.
return Convert.ToBase64String(mStream.ToArray());
}
}
}
//我打"红字"部分报错了!
Specified key is not a valid size for this algorithm.
[解决办法]该加密算法，key值要8个字节长度。
[解决办法]byte[] values = Convert.FromBase64String(strToEn);
