Crypt::DH is a Diffie-Hellman key exchange system.

SYNOPSIS

use Crypt::DH;
my $dh = Crypt::DH->new;
$dh->g($g);
$dh->p($p);

## Generate public and private keys.
$dh->generate_keys;

$my_pub_key = $dh->pub_key;

## Send $my_pub_key to "other" party, and receive "other"
## public key in return.

## Now compute shared secret from "other" public key.
my $shared_secret = $dh->compute_secret( $other_pub_key );

Crypt::DH is a Perl implementation of the Diffie-Hellman key exchange system. Diffie-Hellman is an algorithm by which two parties can agree on a shared secret key, known only to them. The secret is negotiated over an insecure network without the two parties ever passing the actual shared secret, or their private keys, between them.

OpenSSH LDAP Public Key patch provides an easy way of centralizing strong user authentication by using an LDAP server for retrieving public keys instead of ~/.ssh/authorized_keys.
It uses the standard core.schema/nis.schema and strongAuthenticationUser object class, which can simplify login centralization but could introduce serious security flaws if the LDAP server is not correctly configured.
Enhancements:
- A memory leak has been fixed.
- A potential LDAP filter injection if a username has strange characters in it [()*] has been fixed.
