Symmetric Encryption - 對稱式加密，其特色在於加解密所使用的金鑰(key)是相同的!
兩方要進行秘密訊息的傳送之前，必須協議出一個共同的，用來加解密的金鑰(key)以及所使用的演算法；如此一來訊息一來一往之前才可以被正確的加解密。
當然這樣的方式會衍生出一些問題，因此才會有 Asymmetric Encryption(非對稱式加密) 的產生，來改善一些 Symmetric Encryption 的缺點；然而 Symmetric Encryption 在實際的應用上有其實用性，因此目前還是持續不斷的被使用當中。
在加解密運作的機制中，有兩大重要部分，除了金鑰(key)之外，另外一個即為加解密所使用的演算法(algorithm)。
在實際應用上，金鑰(key)是一個檔案，內容為一群無意義的英文與數字的集合，長度範圍有可能介於 64~1024 bits (甚至更大) 之間，妥善由通訊雙方秘密保管好。

Write two short paragraphs about where you live. In the first paragraph describe your neighborhood, and in the second paragraph describe your home.
I live a big community on a mountain in Xindian. There is only one convenient stroe in my neighborhood. There isn't enough much public transportation and parking. The sidewlks should be cleaner. There aren't any restaurants in my neighborhood, but there is a park in my neighborhood. Children can play in the park. It is really quiet and safe. I think my community is not perfect, but it's good enough for me.
I living in a old apartment. There is enough closet space for me, but there is not enough closet space for my wife, and the bathrooms aren't modern enough. I have a stove, washing machine and a refrigerator. They all work pretty well. My kitchen and dining are are big enough for me. My walls were just painted 2 years ago, so I feel my living rooms is comfortable enough. Due to living on the mountain, My rooms are really bright, but they are really cold and damp in winter.
