secret message

基本解释

I gave the king his tribute and I also told him that I needed to tell him a secret message from God, privately.
獻完貢品以後，我告訴他，上帝說了一個秘密，讓我私下轉述他。
“Next, you dip a toothpick into the lemon juice, like this, ” I said. “And you write a secret message on plain white paper.”
“接著，用一根牙簽沾上檸檬汁，像這樣，”我說，“然後在白紙上寫下一條秘密的消息。”
A research team at Harvard analyzed the secret message, and, according to Lafferty’s summary of its findings, it had never seen “sixteenth-century ink act as it does on that particular document.”
哈彿大學研究小組分析了秘密信息。根據拉弗蒂的調查結果摘要顯示，沒有哪個16世紀的墨水和“那個字條上的”一樣。

You can brute force it and unfortunately, the so-called Caesar cipher is not very secure because if you assume, for our purposes in English alphabet with 26 characters, say all lowercase for all uppercase, my God, you only have to try like 24, 25, 26 possible rotations until you can figure out what his secret message is.
你可以強行解密但是不幸地是，所謂的凱撒密碼不是很安全的,因爲如果假設，對於我們的26個字符的字母表,指明所有的小寫爲大寫，我的天，你衹要試24，25次，26次就可以解答出,密文的內容。

It's a secret number so that if Julius Caesar scrambled his message with the key 13, well, then the recipient had better know what that number is or realistically, -- and this is why it's kind of hard to buy -- into some of these age old algorithms, -- what would an alternative approach be to figuring out Julius Caesar's messages to his generals if he didn't know that secret number was 13?
它是一個機密的數字，以至於,如果凱撒大帝使用密鈅13加密了它的消息，然後接收者最好知道那個數字是什麽,實際上--這就是爲什麽很難,破解這些古老的算法-,有什麽變換方法使凱撒大帝的將軍,可以解密凱撒大帝的消息，如果他不知道,那個機密數字是13呢？
