言：从HTTP到HTTPS的质变
当用户访问微爱帮平台时，地址栏中醒目的绿色锁标志字样不仅是技术标识，更是信任的象征。作为处理敏感通信服务的平台，我们选择了最高级别的扩展验证（EV）SSL证书，这背后是对用户安全与隐私的坚定承诺。
第一章：HTTPS核心机制解析
1.1 HTTPS基础架构
HTTP + SSL/TLS = HTTPS
├─ 传输层：TCP可靠连接
├─ 安全层：SSL/TLS加密隧道
└─ 应用层：HTTP协议通信1.2 SSL/TLS握手流程
// 简化的TLS 1.3握手过程
class TLSHandshake {
async performHandshake(client, server) {
// 1. Client Hello
const clientHello = {
version: 'TLS 1.3',
cipherSuites: ['TLS_AES_256_GCM_SHA384'],
random: generateRandom(32),
extensions: ['server_name: www.weiaibang.com']
};
// 2. Server Hello + Certificate
const serverHello = {
version: 'TLS 1.3',
cipherSuite: 'TLS_AES_256_GCM_SHA384',
random: generateRandom(32),
certificate: await this.getEVCertificate(),
extensions: ['key_share']
};
// 3. 密钥交换（前向安全）
const sharedSecret = this.keyExchange(
client.privateKey,
server.publicKey
);
// 4. 生成会话密钥
const sessionKeys = this.deriveKeys(sharedSecret);
// 5. 加密通道建立
return new EncryptedChannel(sessionKeys);
}

2.1 四大安全支柱
HTTPS安全四重保障：
1. 数据加密
└─ 传输过程全加密，防止窃听
2. 身份认证
└─ 证书验证身份，防止冒充
3. 数据完整性
└─ MAC验证，防止篡改
4. 抗重放攻击
└─ 序列号机制，防止重放2.2 具体作用详解
