+ * If the implementation of psa_import_key() supports other formats
+ * beyond the format specified here, the output from psa_export_key()
+ * must use the representation specified here, not the original

+ *
+ * For standard key types, the output format is as follows:
+ *
+ * - For symmetric keys (including MAC keys), the format is the
+ *   raw bytes of the key.
+ * - For DES, the key data consists of 8 bytes. The parity bits must be
+ *   correct.
+ * - For Triple-DES, the format is the concatenation of the
+ *   two or three DES keys.
+ * - For RSA key pairs (#PSA_KEY_TYPE_RSA_KEYPAIR), the format
+ *   is the non-encrypted DER encoding of the representation defined by
+ *   PKCS\#1 (RFC 8017) as `RSAPrivateKey`, version 0.

+ *   ```
+ * - For DSA private keys (#PSA_KEY_TYPE_DSA_KEYPAIR), the format

+ * \brief Export a public key or the public part of a key pair in binary format.
+ *
+ * The output of this function can be passed to psa_import_key() to
+ * create an object that is equivalent to the public key.
+ *
+ * This specification supports a single format for each key type.
+ * Implementations may support other formats as long as the standard
+ * format is supported. Implementations that support other formats
+ * should ensure that the formats are clearly unambiguous so as to
+ * minimize the risk that an invalid input is accidentally interpreted
+ * according to a different format.
+ *
+ * For standard key types, the output format is as follows:
+ * - For RSA public keys (#PSA_KEY_TYPE_RSA_PUBLIC_KEY), the DER encoding of
+ *   the representation defined by RFC 3279 &sect;2.3.1 as `RSAPublicKey`.
+ *   ```
+ *   RSAPublicKey ::= SEQUENCE {
+ *      modulus            INTEGER,    -- n
+ *      publicExponent     INTEGER  }  -- e
+ *   ```
+ * - For elliptic curve public keys (key types for which
+ *   #PSA_KEY_TYPE_IS_ECC_PUBLIC_KEY is true), the format is the uncompressed
+ *   representation defined by SEC1 &sect;2.3.3 as the content of an ECPoint:
+ *   Let `m` be the bit size associated with the curve, i.e. the bit size of
+ *   `q` for a curve over `F_q`. The representation consists of:
+ *      - The byte 0x04;
+ *      - `x_P` as a `ceiling(m/8)`-byte string, big-endian;
+ *      - `y_P` as a `ceiling(m/8)`-byte string, big-endian.
+ *
+ * For other public key types, the format is the DER representation defined by
+ * RFC 5280 as `SubjectPublicKeyInfo`, with the `subjectPublicKey` format
+ * specified below.
+ * ```
+ * SubjectPublicKeyInfo  ::=  SEQUENCE  {
+ *      algorithm          AlgorithmIdentifier,

+ *   with the OID `id-dsa`,
+ *   and with the parameters `DSS-Parms`.

+ * input parameter if: (1) they may come from the outside world (such as the
+ * network, the filesystem, etc.) or (2) not validating them could result in
+ * internal memory errors such as overflowing a buffer controlled by the
+ * library. On the other hand, it doesn't attempt to validate parameters whose
+ * values are fully controlled by the application (such as pointers).
+ *
+ * When this flag is defined, the library additionally attempts to validate
+ * parameters that are fully controlled by the application, and should always
+ * be valid if the application code is fully correct and trusted.
+ *
+ * For example, when a function accepts as input a pointer to a buffer that may
+ * contain untrusted data, and its documentation mentions that this pointer
+ * must not be NULL:
+ * - the pointer is checked to be non-NULL only if this option is enabled
+ * - the content of the buffer is always validated
+ *
+ * When this flag is defined, if a library function receives a parameter that
+ * is invalid, it will:
+ * - invoke the macro MBEDTLS_PARAM_FAILED() which by default expands to a
+ *   call to the function mbedtls_param_failed()
+ * - immediately return (with a specific error code unless the function
+ *   returns void and can't communicate an error).
+ *
+ * When defining this flag, you also need to:
+ * - either provide a definition of the function mbedtls_param_failed() in
+ *   your application (see platform_util.h for its prototype) as the library
+ *   calls that function, but does not provide a default definition for it,
+ * - or provide a different definition of the macro MBEDTLS_PARAM_FAILED()
+ *   below if the above mechanism is not flexible enough to suit your needs.

+ *              Note that you may define this macro to expand to nothing, in

+ *              definitions. However, you will then be notified about invalid
