http:// and https://

What is the difference between http and https ?

**The main difference between http:// and https:// is it's all about keeping you secure** HTTP stands for Hyper Text Transfer Protocol.
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.
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.
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://.
If it doesn't, You should NEVER enter sensitive information, such as a credit card number, Social Security #, etc.

「http」 跟「https」有何不同嗎?

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。
這就是為什麼你不要在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。
如果不是, 請勿輸入敏感資料, 諸如信用卡號碼, 工卡號碼, … 等等。
