怎么快速用程序一对一文字解密

用在线工具对文字加密解密，步骤如下：

1、打开在线工具官方网站。

2、棚搜点击菜单栏的“文字加密解密”。

3、最后我们在瞎燃这里就可以使用在线工具的文字加密解密了。

加密技术磨和虚是最常用的安全保密手段，利用技术手段把重要的数据变为乱码（加密）传送，到达目的地后再用相同或不同的手段还原（解密）。

'这是我从网上找到的一段加密解密睁察的代码，很不错，正键应该符合要求。

'文本框的multiline属性是用来设置是否可以接受多行文本，只能在窗体上手工设置。

'文本框的scrollbars属性是用来设置是悉清茄否有垂直和水平滚动条的，也只能在窗体上手工设置。

'keyAscii不清楚是作什么用的。

'两个StrConv函数用的太好了，我没想到能处理的这么简单。

如果你不是菜鸟,那我就不和你解释C和C++的关系了,还有我就是按照你的要求做的,难道你不知道文件重定向吗??? //这个程序太简单庆友了。。我就不誉陵槐开vc直接在这写给你了。。。差不多就是这样。。汪宏。。。。

#include <stdio.h>

int main( int argv, char *args[] ){

char c

int op = args[3][0] == '0' ? 1 : -1

freopen( args[1], "r", stdin )

freopen( args[2], "w", stdout )

while( ( c = getchar() ) != -1 ){

if( c >= 'A' &&c <= 'Z' ){

c = ( c - 'A' + op + 26 ) % 26 + 'A'

}

printf( "%c", c )

}

return 0

}
