NAME
       RSA_size - get RSA modulus size

SYNOPSIS
        #include <openssl/rsa.h>

        int RSA_size(const RSA *rsa);

DESCRIPTION
       This function 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->n must not be NULL.

RETURN VALUE
       The size in bytes.

SEE ALSO
       rsa(3)

HISTORY
       RSA_size() is available in all versions of SSLeay and OpenSSL.
