如需了解您的信息，我希望大家回复让它听起来像你好b / b
是老板，我们是你的仆人，我们必须做你说的话。我知道
你不是故意听起来那样的。我建议你避免使用期待
回复等字样。
我也建议您对请这个词进行一些研究。 。
*我必须在加密应用程序中处理超过64位的数字，如128位。
*例如，如果我想添加两个128位数我应该怎么做
C.
要么使用现有的bignum库：
http://www.gnu.org/software/gmp/ （GMP）
http://indigo.ie/~mscott/ （Miracl）
或自己编写。
*请以示例解释我。
Hi All,
I m Halid Umar, network security research student. I will explain
my situation and give me hint if you can. I expect reply from you all.
For your information, "I expect reply from you all" makes it sound like you
are the boss, we are your servants, and we have to do what you say. I know
you don''t mean to sound like that. I suggest you avoid the words "expect
reply".
I recommend, also, that you do a little research into the word "please".
* I have to handle numbers that have more than 64 bit like 128bit in
cryptography applications.
* For example, if i want to add two 128 bit numbers what should i do in
C.
Either use an existing bignum library:
http://www.gnu.org/software/gmp/ (GMP)
http://indigo.ie/~mscott/ (Miracl)
or write your own.
* Please explain me with example please.
啊！你看？你知道这个词。 :-)

你好Mr.Richard，
我真的很抱歉我为这个问题设定了句子。
因为我不是母语英语，所以我没有尊重错误的句子
。真的，我不是那个意思。请为我道歉
因为我的英语不好。我也在提高英语水平。
感谢您的快速回复，我很抱歉。

Hello Mr.Richard,
I am really sorry for the sentence i have framed for the question.
无需道歉。我没有被冒犯。我只是想帮助你
避免让一些更敏感的灵魂在这里冒犯。
无论如何，就像我说的，你要么GMP，Miracl，或者充足的时间和
咖啡。 :-)

No need to apologise. I was not offended. I was just trying to help you to
avoid giving offence to some of the more sensitive souls in here.
Anyway, like I said, you want either GMP, Miracl, or plenty of time and
coffee. :-)
