Expand description

\brief Check usage of certificate against extendedKeyUsage.

\param crt Leaf certificate used. \param usage_oid Intended usage (eg MBEDTLS_OID_SERVER_AUTH or MBEDTLS_OID_CLIENT_AUTH). \param usage_len Length of usage_oid (eg given by MBEDTLS_OID_SIZE()).

\return 0 if this use of the certificate is allowed, MBEDTLS_ERR_X509_BAD_INPUT_DATA if not.

\note Usually only makes sense on leaf certificates.
