- *
- * Set the initial seed and set up the entropy source for future reseeds.
- *
- * A typical choice for the \p f_entropy and \p p_entropy parameters is
- * to use the entropy module:
- * - \p f_entropy is mbedtls_entropy_func();
- * - \p p_entropy is an instance of ::mbedtls_entropy_context initialized
- *   with mbedtls_entropy_init() (which registers the platform's default
- *   entropy sources).
- *
- * You can provide a personalization string in addition to the
- * entropy source, to make this instantiation as unique as possible.
- *
- * \note                By default, the security strength as defined by NIST is:
- *                      - 128 bits if \p md_info is SHA-1;
- *                      - 192 bits if \p md_info is SHA-224;
- *                      - 256 bits if \p md_info is SHA-256, SHA-384 or SHA-512.
- *                      Note that SHA-256 is just as efficient as SHA-224.
- *                      The security strength can be reduced if a smaller
- *                      entropy length is set with
- *                      mbedtls_hmac_drbg_set_entropy_len().
- *
- * \note                The default entropy length is the security strength
- *                      (converted from bits to bytes). You can override
- *                      it by calling mbedtls_hmac_drbg_set_entropy_len().

- * \note                During the initial seeding, this function calls
- *                      the entropy source to obtain a nonce
