unity3d中求字符串md5

• 方法一：此方法可在Android正常生成md5

    public string GetMD5(string msg)
    {
        MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
        byte[] data = System.Text.Encoding.UTF8.GetBytes(msg);
        byte[] md5Data = md5.ComputeHash(data, 0, data.Length);
        md5.Clear();  

        string destString = "";
        for (int i = 0; i < md5Data.Length; i++) {
            destString += System.Convert.ToString(md5Data[i], 16).PadLeft(2, ‘0‘);
        }
        destString = destString.PadLeft(32, ‘0‘);
        return destString;
    }

• 方法二：此方法在Android中md5对象为null，不能正常生成md5值

    public string GetMD5(string msg)
    {
        System.Security.Cryptography.MD5 md5 = System.Security.Cryptography.MD5.Create();
        byte[] inputBytes = System.Text.Encoding.ASCII.GetBytes(msg);
        byte[] hash = md5.ComputeHash(inputBytes);
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < hash.Length; i++)
        {
            sb.Append(hash[i].ToString("X2"));
        }
        return sb.ToString();
    }
