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...
Perform the SSL handshake. int mbedtls_ssl_handshake_step (mbedtls_ssl_context *ssl) Perform a single step of the SSL handshake. int mbedtls_ssl_renegotiate (mbedtls_ssl_context *ssl) Initiate an SSL renegotiation on the running connection. int mbedtls_ssl_read (mbedtls_ssl_context *ssl,...
I actually have another way of triggering a crash inmbedtls_ssl_handshake()on the server side, which I think, also comes down tombedtls_ssl_fetch_input(). Its triggered by loading the client with a self-signed certificate and sayingmbedtls_ssl_conf_authmode (&tlsConf, MBEDTLS_SSL_VERIFY_O...
#define MBEDTLS_ERR_SSL_BAD_HS_CLIENT_HELLO -0x7900 /**< Processing of the ClientHello handshake message failed. */ 00079 #define MBEDTLS_ERR_SSL_BAD_HS_SERVER_HELLO -0x7980 /**< Processing of the ServerHello handshake message failed. */ ...
The error code returned by thembedtls_ssl_handshakeis fixed at -17280 (-0x4380) (MBEDTLS_ERR_RSA_VERIFY_FAILED). I've noticed that some times the preceeding handshake's error code is -17168 (-0x4310), which I've tried to find the represented meaning, but failed to, nearest assumption...

Don't perform handshake steps inside mbedtls_ssl_read() or mbedtls_ssl_write(). Instead, have the user call mbedtls_ssl_handshake(). The goal is to simplify these functions and reduce the errors (especially “non-error errors” like MBEDTL...
int mbedtls_ssl_handshake_client_step( mbedtls_ssl_context *ssl ) 输入参数为ssl_context为安全连接的配置参数,包含了握手状态、握手参数、会话数据、客户端ID以及相关回调入口等参数。 以下程序摘自ssl_tls.c文件,可以看出mbed根据宏定义分别实现了server端和client端 ...
