从另外两个代码创建新代码！ [英] create new code from two other codes !

问题描述

朋友，
我有一个包含三个文本框的winform:
代码1:[...]
code2:[...]
code3:[...]

用户具有code1和code2，我想同时使用code1和code2生成一个代码(code3).
我应该使用哪种算法?它应该功能强大并且不容易被黑客入侵！
我应该在网络上搜索什么问题！?
它与哈希有关吗?如果可以的话，我该如何学习?

对不起，我的英语不好.

hi friends,
I have a winform that contains three textboxes:
code1 : [ ... ]
code2 : [ ... ]
code3 : [ ... ]

Users have the code1 and code2, i want to generate a code ( code3 ) by using both code1 and code2.
what algorithm should i use ? it should be powerful and it shouldn''t be easy to hack !
what issue should i search in the web !?
is it related to hashing !? if so how could i learn it?

excuse my bad english.
thanks in advance.

推荐答案

简单:对两个代码进行XOR.

缺点:
-知道其中两个代码的人都可以轻松地处理第三个代码.
-代码长度必须相等.或者您必须延长较短的那个.


组合需要满足哪些要求?使用改善问题 [

Simple: XOR both codes.

Drawbacks:
- Whoever knows two of the codes can esily process the third.
- Codes must equal in length. Or you have to extend the shorter one.
