https

  • http的安全形式.
  • 所以的http请求和响应数据在网络发送前,都要进行加密.
  • http下面提供一个传输级的安全层(位于应用层和传输层之间).

对称加密 - 编/解码使用相同密钥算法

不对称加密 - 编/解码使用不同密钥算法

  • SSL(Secure Sockets Layer 安全套接层)是二进制协议

  • 过程

    1. 客户端建立一条到服务器端口443的连接.
    2. 当建立TCP连接,客户端和服务器就会初始化SSL层,进行握手.
    3. 对加密参数进行沟通,交换密钥.
    4. 若密钥交换成功,验证通过,则握手完成.
    5. 客户端将请求报文发生给安全层.
