If something was "present in all versions" of SSLeay, or if it was added to a version of SSLeay (and therefore predates OpenSSL), remove mention of it. Documentation history now starts with OpenSSL. Remove mention of all history before OpenSSL 0.9.8, inclusive. Remove all AUTHOR sections. Reviewed-by: Tim Hudson <tjh@openssl.org>

=head1 NAME
|
|
|
|
DH_size, DH_bits - get Diffie-Hellman prime size
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/dh.h>
|
|
|
|
int DH_size(const DH *dh);
|
|
|
|
int DH_bits(const DH *dh);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
DH_size() returns the Diffie-Hellman prime size in bytes. It can be used
|
|
to determine how much memory must be allocated for the shared secret
|
|
computed by DH_compute_key().
|
|
|
|
DH_bits() returns the number of significant bits.
|
|
|
|
B<dh> and B<dh-E<gt>p> must not be B<NULL>.
|
|
|
|
=head1 RETURN VALUE
|
|
|
|
The size.

|
=head1 HISTORY
|
|
|
|
