Here is some code to do it! The basic principle is simply to multiply
the ASCII code for each letter by the weighting in the string. This can
not return you the old string (ie. its one-way), so it is more secure.
However more than 1 password may have the same number after encrypting.
Hope this helps


#include <stdio.h>

void main()
{
        int     total = 0;
        char    password[20];
        int     i;

        gets(password);
        for (i = 0; i < strlen(password); total += password[i] * i++);
        printf("Encrypted value is %d\n", total);
}
