:orphan: Client Secure Class ------------------- Methods and properties described in this section are specific to ESP8266. They are not covered in `Arduino WiFi library `__ documentation. Before they are fully documented please refer to information below. Supported crypto ~~~~~~~~~~~~~~~~ In the background the library `axtls `_ is used. The library supports only rsa certificates and no new eliptic curve certificates. TLSv1.2 is supported since SDK 2.4.0-rc1. The following ciphers and digests are supported by `specification `_: * Symmetric Ciphers * AES128-SHA * AES256-SHA * AES128-SHA256 * AES256-SHA256 * Asymmetric Ciphers * RSA 512/1024/2048/4096 bit encryption/decryption. * RSA signing/verification * Digests * SHA1 * MD5 * SHA256/384/512 * HMAC-SHA1 * HMAC-MD5 * HMAC-SHA256 loadCertificate ~~~~~~~~~~~~~~~ Load client certificate from file system. .. code:: cpp loadCertificate(file) *Declarations* .. code:: cpp #include #include #include const char* certyficateFile = "/client.cer"; *setup() or loop()* .. code:: cpp if (!SPIFFS.begin()) { Serial.println("Failed to mount the file system"); return; } Serial.printf("Opening %s", certyficateFile); File crtFile = SPIFFS.open(certyficateFile, "r"); if (!crtFile) { Serial.println(" Failed!"); } WiFiClientSecure client; Serial.print("Loading %s", certyficateFile); if (!client.loadCertificate(crtFile)) { Serial.println(" Failed!"); } // proceed with connecting of client to the host setCertificate ~~~~~~~~~~~~~~ Load client certificate from C array. .. code:: cpp setCertificate (array, size) For a practical example please check `this interesting blog `__. Other Function Calls ~~~~~~~~~~~~~~~~~~~~ .. code:: cpp bool verify (const char *fingerprint, const char *domain_name) void setPrivateKey (const uint8_t *pk, size_t size) bool loadCertificate (Stream &stream, size_t size) bool loadPrivateKey (Stream &stream, size_t size) template bool loadPrivateKey (TFile &file) Documentation for the above functions is not yet prepared. For code samples please refer to separate section with `examples `__ dedicated specifically to the Client Secure Class.
