C语言的隐藏输入

使用libncurses.so实现隐藏输入,即用 * 掩盖终端输入密码明文

源代码 test.c

#include <stdio.h>
#include <curses.h>

void main()
{
    char pasword[10], ch;
    int i;

    WINDOW * win=  initscr();
    cbreak();
    noecho();

    printf("Enter the password <any 8 characters>: ");

    for(i=0; i<8; i++)
    {
        ch = getchar();
        pasword[i] = ch;
        printf("*");
    }
    pasword[i] = '\0';

    endwin();


    /*If you want to know what you have entered as password, you can print it*/
    printf("\nYour password is :");

    for(i=0;i<8;i++)
    {
        printf("%c",pasword[i]);
    }
    printf("\n");
}
           

Makefie:

test:
        gcc test.c -o test -lncurses
clean:
        rm -rf test
           

编译并运行:

# make
gcc test.c -o test -lncurses
# ./test
*nter the password <any 8 characters>: *******
Your password is :12345678
