HTTPS是什么？SSL TLS又是什么？.pdf
从今天开始，我们将开启一个新的“安全篇”，讲述安全相关的 HTTPS、SSL 和 TLS。第 14 讲讲了 HTTP 的一些缺点，其中一个是“无状态”，通过添加 cookie 来解决，另外两个缺点——“明文”和“不安全”只是 HTTP 本身。 无法解决，需要引入新的HTTPS协议。
为什么要有 HTTPS？
简单的答案是“因为 HTTP 不安全”。
(Starting today, we will open a new "security chapter" on security related HTTPS, SSL and TLS.Chapter 14 talks about some disadvantages of HTTP. One of them is "stateless", which is solved by adding cookies. The other two disadvantages - "plaintext" and "unsafe" are just HTTP itself. Cannot be solved. A new HTTPS protocol needs to be introduced.Why HTTPS?The simple answer is "because HTTP is not secure".)
