mbedtls_mpi_core_read_be() function

Import X from unsigned binary data, big-endian. The MPI needs to have enough limbs to store the full value (including any most significant zero bytes in the input).

Summary

Declaration

Definition

from bignum_core.h:258

int mbedtls_mpi_core_read_be(mbedtls_mpi_uint *X, size_t X_limbs, const unsigned char *input, size_t input_length);

Implemented in bignum_core.c:226

Arguments

Argument

Description

The address of the MPI. May only be #NULL if \p X_limbs is 0 and \p input_length is 0.

X_limbs

The number of limbs of \p X.

input

The input buffer to import from. May only be #NULL if \p input_length is 0.

input_length

The length in bytes of \p input.

Return value

\c 0 if successful. #MBEDTLS_ERR_MPI_BUFFER_TOO_SMALL if \p X isn't large enough to hold the value in \p input.
