mbedtls_mpi_mul_mpi() function

Perform a multiplication of two MPIs: X = A * B

Syntax

int mbedtls_mpi_mul_mpi( mbedtls_mpi *X,     const mbedtls_mpi *A,     const mbedtls_mpi *B );
Implemented in bignum.c:1393

Arguments

X

The destination MPI. This must point to an initialized MPI.

A

The first factor. This must point to an initialized MPI.

B

The second factor. This must point to an initialized MPI.

Return value

\c 0 if successful. #MBEDTLS_ERR_MPI_ALLOC_FAILED if a memory allocation failed. Another negative error code on different kinds of failure.
