public static byte[] XORDecrypt(byte[] encoded, string Key)
{
byte[] key = Encoding.ASCII.GetBytes(Key);
for (int i = 0; i < encoded.Length; i++) encoded[i] ^= (byte)(key[i % key.Length] >> (i + key.Length) & 255);
return encoded;
}

But I think I can do it ... I think I can do your work myself
klimi
You sure you can't do it yourself?

I don't understand anything in c++ but I urgently need this code
Dima
no one is gotta do this.

all my attempts are in vain

Dima
why would you need exactly this c# code, while there are done xor examples for c++, like this https://kylewbanks.com/blog/Simple-XOR-Encryption-Decryption-in-Cpp

int a = 2;
char b = a;
At the second line, is type of b converted to an int ?
dont think too much about types. in such cases, the value of the car is just put intk the int
BinaryByter
cpp is FAR less type secure than you might think

ascii values are numbers
Yeah
for (int I = 0; I <= 255; I++)
printf("%d = %c", I, I);

Need alternative for if operator
Anyone knows except '?' operator
Nikolas
why do you need "alternatives" to the if operator?
Nikolas
(which is not an operator to be precise)
BinaryByter
Need alternative for if operator
Anyone knows except '?' operator
asm ("cmp a, b");
BinaryByter
🙃
BinaryByter
Im practicing the organ
BinaryByter
so no
BinaryByter
Im sure that Dima would love to help you out with cmp though!
Dima
use strcmp
BinaryByter
of course it can
BinaryByter
if you know how computers work 😏
BinaryByter
Yea?
BinaryByter
just typecast the int to a char*
BinaryByter
well you might need a char after the ind for null termination 😂😂
BinaryByter
I answered his question of 'does it work with ints'
BinaryByter
Didnt say you should use that
BinaryByter
😂😂😂😂

strcmp compares each char in a string
Anonymous
and each char is stored as an ASCII

So it's comparing numbers in the end.

😂btw it's not !false

In ASCII

And 9 is 39

Ever tried 65 - 'A';
Anonymous
It's 48 in ASCII
BinaryByter
Well not really
BinaryByter
but basically

printf("%d", 65 - 'A');

Hehehehhe
You turned your argument against yourself!!

Never tried it though
