RSA_size, RSA_bits - get RSA modulus size
#include <openssl/rsa.h>
int RSA_size(const RSA *rsa);
int RSA_bits(const RSA *rsa);
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.
The size.

RSA_bits()
was added in OpenSSL 1.1.0.
