+ * \brief   The Advanced Encryption Standard (AES) specifies a FIPS-approved
+ *          cryptographic algorithm that can be used to protect electronic
+ *          data.
+ *
+ *          The AES algorithm is a symmetric block cipher that can
+ *          encrypt and decrypt information. For more information, see
+ *          <em>FIPS Publication 197: Advanced Encryption Standard</em> and
+ *          <em>ISO/IEC 18033-2:2006: Information technology -- Security

+ * use of r7 below, unless -fomit-frame-pointer is passed. Unfortunately,
+ * passing that option is not easy when building with yotta.
+ *
+ * On the other hand, -fomit-frame-pointer is implied by any -Ox options with
+ * x !=0, which we can detect using __OPTIMIZE__ (which is also defined by
+ * clang and armcc5 under the same conditions).
+ *
+ * So, only use the optimized assembly below for optimized build, which avoids
+ * the build error and is pretty reasonable anyway.

+/**
+ * \def MBEDTLS_ECP_INTERNAL_ALT
+ *
+ * Expose a part of the internal interface of the Elliptic Curve Point module.
+ *
+ * MBEDTLS_ECP__FUNCTION_NAME__ALT: Uncomment a macro to let mbed TLS use your
+ * alternative core implementation of elliptic curve arithmetic. Keep in mind
+ * that function prototypes should remain the same.
+ *
+ * This partially replaces one function. The header file from mbed TLS is still
+ * used, in contrast to the MBEDTLS_ECP_ALT flag. The original implementation
+ * is still present and it is used for group structures not supported by the
+ * alternative.
+ *
+ * Any of these options become available by defining MBEDTLS_ECP_INTERNAL_ALT
+ * and implementing the following functions:
+ *      unsigned char mbedtls_internal_ecp_grp_capable(
+ *          const mbedtls_ecp_group *grp )
+ *      int  mbedtls_internal_ecp_init( const mbedtls_ecp_group *grp )
+ *      void mbedtls_internal_ecp_deinit( const mbedtls_ecp_group *grp )
+ * The mbedtls_internal_ecp_grp_capable function should return 1 if the
+ * replacement functions implement arithmetic for the given group and 0
+ * otherwise.
+ * The functions mbedtls_internal_ecp_init and mbedtls_internal_ecp_deinit are
+ * called before and after each point operation and provide an opportunity to
+ * implement optimized set up and tear down instructions.
+ *
+ * Example: In case you uncomment MBEDTLS_ECP_INTERNAL_ALT and
+ * MBEDTLS_ECP_DOUBLE_JAC_ALT, mbed TLS will still provide the ecp_double_jac
+ * function, but will use your mbedtls_internal_ecp_double_jac if the group is
+ * supported (your mbedtls_internal_ecp_grp_capable function returns 1 when
+ * receives it as an argument). If the group is not supported then the original
+ * implementation is used. The other functions and the definition of
+ * mbedtls_ecp_group and mbedtls_ecp_point will not change, so your
+ * implementation of mbedtls_internal_ecp_double_jac and
+ * mbedtls_internal_ecp_grp_capable must be compatible with this definition.
+ *
+ * Uncomment a macro to enable alternate implementation of the corresponding
+ * function.

+ *
+ * \brief Diffie-Hellman-Merkle key exchange.
+ *
+ * <em>RFC-3526: More Modular Exponential (MODP) Diffie-Hellman groups for
+ * Internet Key Exchange (IKE)</em> defines a number of standardized
+ * Diffie-Hellman groups for IKE.
+ *
+ * <em>RFC-5114: Additional Diffie-Hellman Groups for Use with IETF
+ * Standards</em> defines a number of standardized Diffie-Hellman
+ * groups that can be used.
+ *
+ * \warning  The security of the DHM key exchange relies on the proper choice
+ *           of prime modulus - optimally, it should be a safe prime. The usage
+ *           of non-safe primes both decreases the difficulty of the underlying
+ *           discrete logarithm problem and can lead to small subgroup attacks
+ *           leaking private exponent bits when invalid public keys are used
+ *           and not detected. This is especially relevant if the same DHM
+ *           parameters are reused for multiple key exchanges as in static DHM,
+ *           while the criticality of small-subgroup attacks is lower for
+ *           ephemeral DHM.
+ *
+ * \warning  For performance reasons, the code does neither perform primality
+ *           nor safe primality tests, nor the expensive checks for invalid
+ *           subgroups. Moreover, even if these were performed, non-standardized
+ *           primes cannot be trusted because of the possibility of backdoors
+ *           that can't be effectively checked for.
+ *
+ * \warning  Diffie-Hellman-Merkle is therefore a security risk when not using
+ *           standardized primes generated using a trustworthy ("nothing up
+ *           my sleeve") method, such as the RFC 3526 / 7919 primes. In the TLS
+ *           protocol, DH parameters need to be negotiated, so using the default
+ *           primes systematically is not always an option. If possible, use
+ *           Elliptic Curve Diffie-Hellman (ECDH), which has better performance,
+ *           and for which the TLS protocol mandates the use of standard
+ *           parameters.

+ * Error code layout.
+ *
+ * Currently we try to keep all error codes within the negative space of 16
+ * bits signed integers to support all platforms (-0x0001 - -0x7FFF). In
+ * addition we'd like to give two layers of information on the error if
+ * possible.
+ *
+ * For that purpose the error codes are segmented in the following manner:
+ *
+ * 16 bit error code bit-segmentation
+ *
+ * 1 bit  - Unused (sign bit)
+ * 3 bits - High level module ID
+ * 5 bits - Module-dependent error code
+ * 7 bits - Low level module errors
+ *
+ * For historical reasons, low-level error codes are divided in even and odd,
+ * even codes were assigned first, and -1 is reserved for other errors.

+ * \param ctx      The RSA public key context.
+ * \param f_rng    The RNG function. Only needed for #MBEDTLS_RSA_PRIVATE.
+ * \param p_rng    The RNG parameter.
+ * \param mode     #MBEDTLS_RSA_PUBLIC or #MBEDTLS_RSA_PRIVATE.
+ * \param md_alg   The message-digest algorithm used to hash the original data.
+ *                 Use #MBEDTLS_MD_NONE for signing raw data.
+ * \param hashlen  The length of the message digest. Only used if \p md_alg is #MBEDTLS_MD_NONE.

+ *
+ * \deprecated     It is deprecated and discouraged to call this function
+ *                 in #MBEDTLS_RSA_PRIVATE mode. Future versions of the library
+ *                 are likely to remove the \p mode argument and have it
+ *                 implicitly set to #MBEDTLS_RSA_PUBLIC.
+ *
+ * \note           Alternative implementations of RSA need not support
+ *                 mode being set to #MBEDTLS_RSA_PRIVATE and might instead

+ *
+ * \note           The \p sig buffer must be as large as the size
+ *                 of \p ctx->N. For example, 128 Bytes if RSA-1024 is used.
+ *
+ * \note           The \p hash_id in the RSA context is the one used for the
+ *                 verification. \p md_alg in the function call is the type of
+ *                 hash that is verified. According to <em>RFC-3447: Public-Key
+ *                 Cryptography Standards (PKCS) #1 v2.1: RSA Cryptography
+ *                 Specifications</em> it is advised to keep both hashes the
+ *                 same. If \p hash_id in the RSA context is unset,
+ *                 the \p md_alg from the function call is used.

+ *      - mbedtls_rsa_deduce_private_exponent
+ *      - mbedtls_rsa_deduce_crt

+ *  (2) Parameter-checking helpers. These are:
+ *      - mbedtls_rsa_validate_params
+ *      - mbedtls_rsa_validate_crt
+ *      They take a set of core or CRT related RSA parameters

+ *
+ *              This function roughly separates the implementation
+ *              of the logic of (D)TLS from the implementation
+ *              of the secure transport.
+ *
+ * \param  ssl  SSL context to use
+ *
+ * \return      0 or non-zero error code.
+ *
+ * \note        A clarification on what is called 'record layer' here
+ *              is in order, as many sensible definitions are possible:
+ *
+ *              The record layer takes as input an untrusted underlying
+ *              transport (stream or datagram) and transforms it into
+ *              a serially multiplexed, secure transport, which
+ *              conceptually provides the following:
+ *
+ *              (1) Three datagram based, content-agnostic transports
+ *                  for handshake, alert and CCS messages.
+ *              (2) One stream- or datagram-based transport
+ *                  for application data.
+ *              (3) Functionality for changing the underlying transform
+ *                  securing the contents.
+ *
+ *              The interface to this functionality is given as follows:
+ *
+ *              a Updating
+ *                [Currently implemented by mbedtls_ssl_read_record]
+ *
+ *                Check if and on which of the four 'ports' data is pending:
+ *                Nothing, a controlling datagram of type (1), or application
+ *                data (2). In any case data is present, internal buffers
+ *                provide access to the data for the user to process it.
+ *                Consumption of type (1) datagrams is done automatically
+ *                on the next update, invalidating that the internal buffers
+ *                for previous datagrams, while consumption of application
+ *                data (2) is user-controlled.
+ *
+ *              b Reading of application data
+ *                [Currently manual adaption of ssl->in_offt pointer]
+ *
+ *                As mentioned in the last paragraph, consumption of data
+ *                is different from the automatic consumption of control
+ *                datagrams (1) because application data is treated as a stream.
+ *
+ *              c Tracking availability of application data
+ *                [Currently manually through decreasing ssl->in_msglen]
+ *
+ *                For efficiency and to retain datagram semantics for
+ *                application data in case of DTLS, the record layer
+ *                provides functionality for checking how much application
+ *                data is still available in the internal buffer.
+ *
+ *              d Changing the transformation securing the communication.
+ *
+ *              Given an opaque implementation of the record layer in the
+ *              above sense, it should be possible to implement the logic
+ *              of (D)TLS on top of it without the need to know anything
+ *              about the record layer's internals. This is done e.g.
+ *              in all the handshake handling functions, and in the
+ *              application data reading function mbedtls_ssl_read.
+ *
+ * \note        The above tries to give a conceptual picture of the
+ *              record layer, but the current implementation deviates
+ *              from it in some places. For example, our implementation of
+ *              the update functionality through mbedtls_ssl_read_record
+ *              discards datagrams depending on the current state, which
+ *              wouldn't fall under the record layer's responsibility
+ *              following the above definition.

+ *
+ *                 The verify callback is a user-supplied callback that

+ *                 int *flags). With the flags representing current flags for

+ *
+ *                 All flags left after returning from the callback
+ *                 are also returned to the application. The function should

+ *                 other than fatal error, as a non-zero return code
+ *                 immediately aborts the verification process. For fatal
+ *                 errors, a specific error code should be used (different

+ *                 be returned at this point), or MBEDTLS_ERR_X509_FATAL_ERROR
