NAME
RSA_size, RSA_bits - get the RSA modulus size
SYNOPSIS
#include <openssl/rsa.h>
int
RSA_size(const RSA *rsa);
int
RSA_bits(const RSA *rsa);
DESCRIPTION
RSA_size() returns the RSA modulus size in bytes. It can be used to
determine how much memory must be allocated for an RSA encrypted value.
RSA_bits() returns the number of significant bits.
rsa and rsa->n must not be NULL.
RETURN VALUES
The size.
