* \param pwd The password to use. For compliance with PKCS#12 §B.1, this
* should be a BMPString, i.e. a Unicode string where each
* character is encoded as 2 bytes in big-endian order, with
* no byte order mark and with a null terminator (i.e. the
* last two bytes should be 0x00 0x00).
* \param pwdlen length of the password (may be 0).
* \param salt Salt buffer to use. This may only be \c NULL when
* \p saltlen is 0.
* \param saltlen length of the salt (may be zero)
* \param mbedtls_md mbedtls_md type to use during the derivation
* \param id id that describes the purpose (can be
* #MBEDTLS_PKCS12_DERIVE_KEY, #MBEDTLS_PKCS12_DERIVE_IV or
* #MBEDTLS_PKCS12_DERIVE_MAC_KEY)
* \param iterations number of iterations
*
* \return 0 if successful, or a MD, BIGNUM type error.
