Function esp_idf_sys::mbedtls_rsa_export_crt

pub unsafe extern "C" fn mbedtls_rsa_export_crt(
    ctx: *const mbedtls_rsa_context,
    DP: *mut mbedtls_mpi,
    DQ: *mut mbedtls_mpi,

) -> c_int

\brief This function exports CRT parameters of a private RSA key.

\note Alternative RSA implementations not using CRT-parameters internally can implement this function based on mbedtls_rsa_deduce_opt().

\param ctx The initialized RSA context. \param DP The MPI to hold \c D modulo P-1, or \c NULL if it need not be exported. \param DQ The MPI to hold \c D modulo Q-1, or \c NULL if it need not be exported. \param QP The MPI to hold modular inverse of \c Q modulo \c P, or \c NULL if it need not be exported.

\return \c 0 on success. \return A non-zero error code on failure.
