NAME

Net::SSH::Perl::Kex::DH16SHA512 - Diffie-Hellman Group 16 SHA512 Key Exchange (RFC3526 "4096-bit MODP Group")

SYNOPSIS

use Net::SSH::Perl::Kex;
my $kex = Net::SSH::Perl::Kex->new;
my $dh16 = bless $kex, 'Net::SSH::Perl::Kex::DH16SHA512';

$dh16->exchange;

DESCRIPTION

Net::SSH::Perl::Kex::DH16SHA512 implements Diffie-Hellman Group 16 SHA512 Key Exchange for Net::SSH::Perl. It is a subclass of Net::SSH::Perl::Kex.

Group 16 Key Exchange uses the Diffie-Hellman key exchange algorithm to produce a shared secret key between client and server, without ever sending the shared secret over the insecure network. All that is sent are the client and server public keys.

Net::SSH::Perl::Kex::DH16SHA512 uses CryptX for the Diffie-Hellman implementation. The p value is set to
