mbed TLS v2.16.3: SSL/TLS communication module

mbed TLS v2.16.3

SSL/TLS communication module

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 `mbedtls_ssl_init()`).
- perform an SSL/TLS handshake (see `mbedtls_ssl_handshake()`).
- read/write (see `mbedtls_ssl_read()` and `mbedtls_ssl_write()`).
- notify a peer that connection is being closed (see `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.
Note that you need to provide for several aspects yourself as mentioned above.
