=head1 NAME
|
|
|
|
RSA_size, RSA_bits - get RSA modulus size
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/rsa.h>
|
|
|
|
int RSA_size(const RSA *rsa);
|
|
|
|
int RSA_bits(const RSA *rsa);
|
|
|
|
=head1 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.
|
|
|
|
B<rsa> and B<rsa-E<gt>n> must not be B<NULL>.
|
|
|
|
=head1 RETURN VALUE
|
|
|
|
The size.

|
|
|
=head1 HISTORY
|
|
|
|
RSA_bits() was added in OpenSSL 1.1.0.
