- I said cryptanalysis and not cryptography, a word you may know better,
我說的是「密碼分析」，而不是你比較熟知的「密碼學」
- because cryptography is about sending a message securely by changing it, often changing it so it looks meaningless.
因為「密碼學」是指為了安全傳送訊息而將其加以改變，這樣訊息就看起來毫無意義

- Using cryptography, we can use hashing to hash the data that's in there and then say whether it's been changed enough, we consign that after the same way that Mike's talked about another videos, and we can also use cryptography to encrypt the data so they can't be sneaked on as it travels.
使用密碼學，我們可以使用散列來對其中的數據進行散列，然後判斷它是否已經被足夠地改變，我們按照 Mike 在另一個視頻中談論的同樣的方式委託它，我們還可以使用密碼學來加密數據，這樣它們在傳輸過程中就不會被偷偷傳播。
