|  | * | 
|  | * The SSL/TLS communication module provides the means to create an SSL/TLS | 
|  | * communication channel. | 
|  | * | 
|  | * The basic provisions are: | 
|  | * - initialise an SSL/TLS context (see \c mbedtls_ssl_init()). | 
|  | * - perform an SSL/TLS handshake (see \c mbedtls_ssl_handshake()). | 
|  | * - read/write (see \c mbedtls_ssl_read() and \c mbedtls_ssl_write()). | 
|  | * - notify a peer that connection is being closed (see \c mbedtls_ssl_close_notify()). | 
|  | * | 
|  | * Many aspects of such a channel are set through parameters and callback | 
|  | * functions: | 
|  | * - the endpoint role: client or server. | 
|  | * - the authentication mode. Should verification take place. | 
|  | * - the Host-to-host communication channel. A TCP/IP module is provided. | 
|  | * - the random number generator (RNG). | 
|  | * - the ciphers to use for encryption/decryption. | 
|  | * - session control functions. | 
|  | * - X.509 parameters for certificate-handling and key exchange. | 
|  | * | 
|  | * This module can be used to create an SSL/TLS server and client and to provide a basic | 
|  | * framework to setup and communicate through an SSL/TLS communication channel.\n | 
|  | * Note that you need to provide for several aspects yourself as mentioned above. |
