4、SSL/TLS握手流程,过程比较复杂,简化就是通信双方校验对方身份,获取对方的公钥,确认加密方式,后续数据进行加密或解密做准备 mbedtls_ssl_handshake 5、校验服务端返回的证书 mbedtls_ssl_get_verify_result 6、如果前面流程顺畅,就可以使用mbedtls_ssl_write,mbedtls_ssl_read收发数据了 7、测试结束后的清理工作 8、...
客户端的实现都在ssl_cli.c里,状态机由mbedtls_ssl_handshake_client_step()处理 服务端的实现则在ssl_srv.c里,状态机由mbedtls_ssl_handshake_server_step()处理 (3)”Client Hello”由函数ssl_write_client_hello()实现报文填充和发送,内容主要包含: Random 32字节随机数,前4字节为当前时间+28字节随机数 Coo...
