While stereotyped repetitions are frowned upon in literature, they serve a useful purpose in manual pages, because it is easier for the user to find certain information if it is always presented in the same way. For that reason, this commit harmonizes the varying formulations in the HISTORY section about which functions, flags, etc. were added in which OpenSSL version. It also attempts to make the pod files more grep friendly by avoiding to insert line breaks between the symbol names and the corresponding version number in which they were introduced (wherever possible). Some punctuation and typographical errors were fixed on the way. Reviewed-by: Tim Hudson <tjh@openssl.org> (Merged from https://github.com/openssl/openssl/pull/7854)

=head1 NAME
|
|
|
|
DH_size, DH_bits, DH_security_bits - get Diffie-Hellman prime size and
|
|
security bits
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/dh.h>
|
|
|
|
int DH_size(const DH *dh);
|
|
|
|
int DH_bits(const DH *dh);
|
|
|
|
int DH_security_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 L<DH_compute_key(3)>.
|
|
|
|
DH_bits() returns the number of significant bits.
|
|
|
|
B<dh> and B<dh-E<gt>p> must not be B<NULL>.
|
|
|
|
DH_security_bits() returns the number of security bits of the given B<dh>
|
|
key. See L<BN_security_bits(3)>.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
DH_size() returns the prime size of Diffie-Hellman in bytes.
|
|
|
|
DH_bits() returns the number of bits in the key.
|
|
|
|
DH_security_bits() returns the number of security bits.
|

=head1 HISTORY
|
|
|
|
The DH_bits() function was added in OpenSSL 1.1.0.
