RSA_SIZE(3)			    OpenSSL			   RSA_SIZE(3)

NAME
       RSA_size, RSA_bits, RSA_security_bits - get RSA modulus size or
       security	bits

SYNOPSIS
	#include <openssl/rsa.h>

	int RSA_size(const RSA *rsa);

	int RSA_bits(const RSA *rsa);

	int RSA_security_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.

       RSA_security_bits() returns the number of security bits of the given
       rsa key.	See BN_security_bits(3).

RETURN VALUES
       RSA_size() returns the size of modulus in bytes.

       DSA_bits() returns the number of	bits in	the key.

       RSA_security_bits() returns the number of security bits.

SEE ALSO
       BN_num_bits(3)

HISTORY
       The RSA_bits() function was added in OpenSSL 1.1.0.
