Hi! ✌️ I need to generate some string in C++ with random characters that can use all letters from "a" to "z" (include capital letters), and all numbers from 0 to 9 there.

And for examples this should looks somehow like this:

SnHXAsOC5XDYLgiKM5ly

Also I want to encrypt that string then by itself:

SnHXAsOC5XDYLgiKM5ly encrypt with SnHXAsOC5XDYLgiKM5ly key.

So, how can I do this in C++? 🤔

Thanks in advance!

FILE *f = popen("curl 'https://www.random.org/passwords/?num=1&len=12&format=plain&rnd=new'", "r");
char s[14];
fread(s, 1, sizeof(s), f);
s[13] = 0;
