眾所周知，應用程序中的數據庫操作需要連接字符串，但如果沒有連接字符串，則無法完成一系列數據庫操作，下文是錯新技術頻道asp.net 字符串加密解密技術的介紹，希望可以幫助到有需要的你們。

///字符串
///密鑰
///返回加密后的字符串
public string DesEncrypt(string inputString, string encryptKey)
{
byte[] byKey = null;
byte[] IV = { 0x12, 0x34, 0x56, 0x78, 0x90, 0xAB, 0xCD, 0xEF };
try
{
byKey = System.Text.Encoding.UTF8.GetBytes(encryptKey.Substring(0, 8));
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
byte[] inputByteArray = Encoding.UTF8.GetBytes(inputString);
MemoryStream ms = new MemoryStream();
CryptoStream cs = new CryptoStream(ms, des.CreateEncryptor(byKey, IV), CryptoStreamMode.Write);
cs.Write(inputByteArray, 0, inputByteArray.Length);
cs.FlushFinalBlock();
return Convert.ToBase64String(ms.ToArray());
}
catch (System.Exception error)
{
//return error.Message;
return null;
}
}
///

///加了密的字符串
///密鑰
///返回解密后的字符串
public string DesDecrypt(string inputString, string decryptKey)
{
byte[] byKey = null;
byte[] IV = { 0x12, 0x34, 0x56, 0x78, 0x90, 0xAB, 0xCD, 0xEF };
byte[] inputByteArray = new Byte[inputString.Length];
try
{
byKey = System.Text.Encoding.UTF8.GetBytes(decryptKey.Substring(0, 8));
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
inputByteArray = Convert.FromBase64String(inputString);
MemoryStream ms = new MemoryStream();
CryptoStream cs = new CryptoStream(ms, des.CreateDecryptor(byKey, IV), CryptoStreamMode.Write);
cs.Write(inputByteArray, 0, inputByteArray.Length);
cs.FlushFinalBlock();
System.Text.Encoding encoding = new System.Text.UTF8Encoding();
return encoding.GetString(ms.ToArray());
}
catch (System.Exception error)
{
//return error.Message;
return null;
}
}
}
}
