One of my questions still remains unresolved. I still don't know why XOR, bit shifting and the like are used for hashes and ciphers in the first place - if there is any mathematical reasoning behind this, why it's exactly these operations and nothing else?
One of my questions still remains unresolved. I still don't knowthe reasons why exactly XOR, bit shifting and the like are is used for hashesis that because XOR has an important property: reversibility. If you XOR a number with a key and ciphers inthen XOR the first place - if there is any mathematical reasoning behind thisresult with same key again, why it's exactly these operations and nothing else?you will get your original number.
- one of the reasons why exactly XOR is used is that because XOR has important property - reversability. if you XOR number with a key and then XOR the result with same key again - you will get your original number.
