Hello,
I'm just writing a little encryption program which sould be able to create
its own random passwords. The code is something like that:
srandom(biostime(0, 0)); // DOS-ticks are used as seed value
unsigned char C = (rand() % 255) + 1; // no null-characters
I can't find any errors in this 2 lines, but the program returns everytime
the same password.
Perhaps I should use a different source for my seed value, but why and what?
BTW: As I checked, biostime() works quiet well, the bug must be somewhere
else...
Thanks.
