NAME ^

Net::SSH::Perl::Kex::DH14SHA256 - Diffie-Hellman Group 14 SHA256 Key Exchange (RFC3526 "2048-bit MODP Group")

SYNOPSIS ^

    use Net::SSH::Perl::Kex;
    my $kex = Net::SSH::Perl::Kex->new;
    my $dh14 = bless $kex, 'Net::SSH::Perl::Kex::DH14SHA256';

    $dh14->exchange;

DESCRIPTION ^

Net::SSH::Perl::Kex::DH14SHA256 implements Diffie-Hellman Group 14 SHA256 Key Exchange for Net::SSH::Perl. It is a subclass of Net::SSH::Perl::Kex.

Group 14 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::DH14SHA256 uses CryptX for the Diffie-Hellman implementation. The p value is set to
