导读关键代码，整合函数，调用方法:login.jsp，logout.jsp，

关键代码

/**

* @param strToEncrypt
* @return

public static String  Md5(String strToEncrypt)
{
char hexDigits[] = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9',
'a', 'b', 'c', 'd', 'e', 'f' };
try
{
byte[] strTemp = strToEncrypt.getBytes();
MessageDigest mdTemp = MessageDigest.getInstance("MD5");
mdTemp.update(strTemp);
byte[] md = mdTemp.digest();

char str[] = new char[j * 2];
int k = 0;
for (int i = 0; i < j; i++)
{

str[k++] = hexDigits[byte0 & 0xf];
}
return new String(str);
}
