I have heard about people starting encryption and thought it may be something I would like, so I checked XOR and can't make any sense of it. So can someone explain to me what XOR is ?
Answer
you take a key, such as 0101, then you use that to XOR your string (in binary format) to achieve an encrypted string.
0101 XOR <-- key
1011 <---- original message
----
1110 <-- send message
You send 1110 to your receiver. That receiver, then takes the received string and XORs it with the key to obtain the original message:
1110 XOR <--- received message
0101 <-- key
----
1011 <--- original message
