浏览器端 公钥不能被篡改但是可以看但中间者可以伪造一堆公私钥进行加密解密在传输- 对数据进行加密 - 密文 - 服务器用私钥 - 可以还原成 - 原文
公钥如何传输才能不被拦截 公钥不传输就不会被拦截用当前服务器私钥生成一个公钥把公钥拷贝到浏览器端。
加密算法 算法名称 盐秘钥
CA认证服务不是防止数据被偷窥而是保证用户访问网站的真实性可以访问到用户真正想要访问的地址防调用网站 如何防调用网站ca.私钥服务器公钥域名公钥的摘要 证书 浏览器再去校验证书明文写谁下发的证书在CA列表里查找对应的下发者用对应的ca.公钥进行解析能解析出来相应的数据则为真的
HTTPS如何进行安全传输 浏览器对称加密 - 服务器非对称加密 - CA的非对称加密
3、浏览器向80端口发送请求
4、得到 加密算法.decode 解密密文
