Field Documentation

n

size_t mbedtls_mpi::n

Total number of limbs in p.

Definition at line 211 of file bignum.h.

p

mbedtls_mpi_uint* mbedtls_mpi::p

Pointer to limbs.

This may be NULL if n is 0.

s

int mbedtls_mpi::s

Sign: -1 if the mpi is negative, 1 otherwise.

The number 0 must be represented with s = +1. Although many library functions treat all-limbs-zero as equivalent to a valid representation of 0 regardless of the sign bit, there are exceptions, so bignum functions and external callers must always set s to +1 for the number zero.

Note that this implies that calloc() or ... = {0} does not create a valid MPI representation. You must call mbedtls_mpi_init().
