NAME ^

Net::SSH::Perl::Kex::DH1 - Diffie-Hellman Group 1 Key Exchange

SYNOPSIS ^

    use Net::SSH::Perl::Kex;
    my $kex = Net::SSH::Perl::Kex->new;
    my $dh1 = bless $kex, 'Net::SSH::Perl::Kex::DH1';

    $dh1->exchange;

DESCRIPTION ^

Net::SSH::Perl::Kex::DH1 implements Diffie-Hellman Group 1 Key Exchange for Net::SSH::Perl. It is a subclass of Net::SSH::Perl::Kex.

Group 1 Key Exchange uses the Diffie-Hellman key exchange algorithm to produce a shared seret 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::DH1 uses Crypt::DH for the Diffie-Hellman implementation. The p value is set to
