mbedtls_mpi_mod_mpi() function

Perform a modular reduction. R = A mod B

Syntax

int mbedtls_mpi_mod_mpi( mbedtls_mpi *R,     const mbedtls_mpi *A,     const mbedtls_mpi *B );
Implemented in bignum.c:1684

Arguments

R

The destination MPI for the residue value. This must point to an initialized MPI.

A

The MPI to compute the residue of. This must point to an initialized MPI.

B

The base of the modular reduction. This must point to an initialized MPI.

Return value

\c 0 if successful. #MBEDTLS_ERR_MPI_ALLOC_FAILED if a memory allocation failed. #MBEDTLS_ERR_MPI_DIVISION_BY_ZERO if \p B equals zero. #MBEDTLS_ERR_MPI_NEGATIVE_VALUE if \p B is negative. Another negative error code on different kinds of failure.
