"http://" 和 "https://" 的差別

"http://" 和 "https://" 的差別 (中英對照)



最近上課，有同學問到"http://" 和 "https://" 的差別，
在此整理如下，同時補充技術性的說明：


"http" & "https" - Do YOU Know The Difference ?
你知道"http" 跟 "https"有何不同嗎?

Once in a while, there is something that comes down the pike that is of real importance.
有時這之間的差異是很重要的

What is the difference between http and https ?
Don't know how many of you are aware of this difference, but it is worth sending to any that do not.....
http和https之間的差異，不知你們有多少人注意到了，但還是值得將此訊息傳送給還不知道的人

**The main difference between http:// and https:// is it's all about keeping you secure** HTTP stands for Hyper Text Transfer Protocol
http://跟https://之間的差異在於網路文字傳送協定標準不同。

The S (big surprise) stands for "Secure".. If you visit a website or web page, and look at the address in the web browser, it will likely begin with the following: http://.
This means that the website is talking to your browser using the regular 'unsecured language. In other words, it is possible for someone to "eavesdrop" on your computer's conversation with the website. If you fill out a form on the website, someone might see the information you send to that site.
這僅一個字母S的差別代表"安全(secure)"，所以http://是該網頁與你的電腦瀏覽器，以一般(非安全)模式在進行互動交談，所以內容有可能遭攔截竊聽；換句話說，你在此類網頁上填寫傳送的資料有可能被有心人士看到。

This is why you never ever enter your credit card number in an http website! But if the web address begins with https://, that basically means your computer is talking to the website in a secure code that no one can eavesdrop on.
這就是為什麼你從不會在http網頁輸入你的信用卡資料! 但如果網址開頭是https://，基本上意謂著，你的電腦是以無人能盗取得安全碼，與該網頁進行互動交談。

You understand why this is so important, right?
你了解為什麼這是如此重要了，對吧?

If a website ever asks you to enter your credit card information, you should automatically look to see if the web address begins with https://.
請在輸入機密資料時確認該網頁開頭是不是https:// 。

If it doesn't, You should NEVER enter sensitive information....such as a credit card number, SS # etc.
如果不是，請勿輸入敏感資料....諸如信用卡號碼，SS # 等等。

PASS IT ON (You may save someone a lot of grief).
請廣為傳送(也許可替人免去一些悲劇)



補充說明：

http是超文本傳輸協定，而https是經過加密的超文本傳輸協定。
它們的區別也就在於一個安全性的問題。
因此，經過加密的https是比較安全的。

HTTP 走的是80端口
HTTPS　走的是443端口
