MQTTAsync_sslProperties defines the settings to establish an SSL/TLS connection using the OpenSSL library. It covers the following scenarios:
Definition at line 1033 of file MQTTAsync.h.
| const char* MQTTAsync_SSLOptions::CApath |
From the OpenSSL documentation: If CApath is not NULL, it points to a directory containing CA certificates in PEM format. Exists only if struct_version >= 2
Definition at line 1094 of file MQTTAsync.h.
| int MQTTAsync_SSLOptions::disableDefaultTrustStore |
Don't load default SSL CA. Should be used together with PSK to make sure regular servers with certificate in place is not accepted. Exists only if struct_version >= 4
Definition at line 1126 of file MQTTAsync.h.
| const char* MQTTAsync_SSLOptions::enabledCipherSuites |
The list of cipher suites that the client will present to the server during the SSL handshake. For a full explanation of the cipher list format, please see the OpenSSL on-line documentation: http://www.openssl.org/docs/apps/ciphers.html#CIPHER_LIST_FORMAT If this setting is ommitted, its default value will be "ALL", that is, all the cipher suites -excluding those offering no encryption- will be considered. This setting can be used to set an SSL anonymous connection ("aNULL" string value, for instance).
Definition at line 1071 of file MQTTAsync.h.
| int MQTTAsync_SSLOptions::enableServerCertAuth |
True/False option to enable verification of the server certificate
Definition at line 1074 of file MQTTAsync.h.
| const char* MQTTAsync_SSLOptions::keyStore |
The file in PEM format containing the public certificate chain of the client. It may also include the client's private key.
Definition at line 1053 of file MQTTAsync.h.
| const char* MQTTAsync_SSLOptions::privateKey |
If not included in the sslKeyStore, this setting points to the file in PEM format containing the client's private key.
Definition at line 1058 of file MQTTAsync.h.
| const char* MQTTAsync_SSLOptions::privateKeyPassword |
The password to load the client's privateKey if encrypted.
Definition at line 1061 of file MQTTAsync.h.
| const unsigned char* MQTTAsync_SSLOptions::protos |
The protocol-lists must be in wire-format, which is defined as a vector of non-empty, 8-bit length-prefixed, byte strings. The length-prefix byte is not included in the length. Each string is limited to 255 bytes. A byte-string length of 0 is invalid. A truncated byte-string is invalid. Check documentation for SSL_CTX_set_alpn_protos Exists only if struct_version >= 5
Definition at line 1135 of file MQTTAsync.h.
| unsigned int MQTTAsync_SSLOptions::protos_len |
The length of the vector protos vector Exists only if struct_version >= 5
Definition at line 1141 of file MQTTAsync.h.
| int(* MQTTAsync_SSLOptions::ssl_error_cb) (const char *str, size_t len, void *u) |
Callback function for OpenSSL error handler ERR_print_errors_cb Exists only if struct_version >= 3
Definition at line 1100 of file MQTTAsync.h.
| void* MQTTAsync_SSLOptions::ssl_error_context |
Application-specific contex for OpenSSL error handler ERR_print_errors_cb Exists only if struct_version >= 3
Definition at line 1106 of file MQTTAsync.h.
| unsigned int(* MQTTAsync_SSLOptions::ssl_psk_cb) (const char *hint, char *identity, unsigned int max_identity_len, unsigned char *psk, unsigned int max_psk_len, void *u) |
Callback function for setting TLS-PSK options. Parameters correspond to that of SSL_CTX_set_psk_client_callback, except for u which is the pointer ssl_psk_context. Exists only if struct_version >= 4
Definition at line 1113 of file MQTTAsync.h.
| void* MQTTAsync_SSLOptions::ssl_psk_context |
Application-specific contex for ssl_psk_cb Exists only if struct_version >= 4
Definition at line 1119 of file MQTTAsync.h.
| int MQTTAsync_SSLOptions::sslVersion |
The SSL/TLS version to use. Specify one of MQTT_SSL_VERSION_DEFAULT (0), MQTT_SSL_VERSION_TLS_1_0 (1), MQTT_SSL_VERSION_TLS_1_1 (2) or MQTT_SSL_VERSION_TLS_1_2 (3). Only used if struct_version is >= 1.
Definition at line 1080 of file MQTTAsync.h.
| char MQTTAsync_SSLOptions::struct_id[4] |
The eyecatcher for this structure. Must be MQTS
Definition at line 1036 of file MQTTAsync.h.
| int MQTTAsync_SSLOptions::struct_version |
The version number of this structure. Must be 0, 1, 2, 3, 4 or 5. 0 means no sslVersion 1 means no verify, CApath 2 means no ssl_error_context, ssl_error_cb 3 means no ssl_psk_cb, ssl_psk_context, disableDefaultTrustStore 4 means no protos, protos_len
Definition at line 1045 of file MQTTAsync.h.
| const char* MQTTAsync_SSLOptions::trustStore |
The file in PEM format containing the public digital certificates trusted by the client.
Definition at line 1048 of file MQTTAsync.h.
| int MQTTAsync_SSLOptions::verify |
Whether to carry out post-connect checks, including that a certificate matches the given host name. Exists only if struct_version >= 2
Definition at line 1087 of file MQTTAsync.h.
