encryption
Hi, I was browsing and found good articles about encryption. However, none of them described why the key lenght is important and what exactly the key is used for. My guess is that could work this way:
0101001101010101010
Key: 01010010101010010101 //the longer the key, the longer unique sequence
XOR or smth: //result
Is this at least a bit how it works or I am missing something? Thanks
