md5 utf8 base64 算法
C# public string MD5(string s){
MD5CryptoServiceProvider MD5CSP = new MD5CryptoServiceProvider();
byte[] MD5Source = Encoding.UTF8.GetBytes(s);
byte[] MD5Out = MD5CSP.ComputeHash(MD5Source);
string ret = Convert.ToBase64String(MD5Out);
return ret;
}
各位大神这个C#加密算法转换成java怎么转换阿,转换之后是怎么样的,教下小弟 --------------------编程问答--------------------

补充：Java , Eclipse
