NAME POE::Component::SSLify - Makes using SSL in the world of POE easy! SYNOPSIS Client-side usage # Import the module use POE::Component::SSLify qw( Client_SSLify ); # Create a normal SocketFactory wheel or something my $factory = POE::Wheel::SocketFactory->new( ... ); # Converts the socket into a SSL socket POE can communicate with eval { $socket = Client_SSLify( $socket ) }; if ( $@ ) { # Unable to SSLify it... } # Now, hand it off to ReadWrite my $rw = POE::Wheel::ReadWrite->new( Handle => $socket, ... ); # Use it as you wish... Server-side usage # !!! Make sure you have a public key + certificate generated via Net::SSLeay's makecert.pl # excellent howto: http://www.akadia.com/services/ssh_test_certificate.html # Import the module use POE::Component::SSLify qw( Server_SSLify SSLify_Options ); # Set the key + certificate file eval { SSLify_Options( 'server.key', 'server.crt' ) }; if ( $@ ) { # Unable to load key or certificate file... } # Create a normal SocketFactory wheel or something my $factory = POE::Wheel::SocketFactory->new( ... ); # Converts the socket into a SSL socket POE can communicate with eval { $socket = Server_SSLify( $socket ) }; if ( $@ ) { # Unable to SSLify it... } # Now, hand it off to ReadWrite my $rw = POE::Wheel::ReadWrite->new( Handle => $socket, ... ); # Use it as you wish... ABSTRACT Makes SSL use in POE a breeze! DESCRIPTION This component represents the standard way to do SSL in POE. NOTES Socket methods doesn't work The new socket this module gives you actually is some tied socket magic, so you cannot do stuff like getpeername() or getsockname(). The only way to do it is to use SSLify_GetSocket and then operate on the socket it returns. Dying everywhere... This module will die() if Net::SSLeay could not be loaded or it is not the version we want. So, it is recommended that you check for errors and not use SSL, like so: eval { use POE::Component::SSLify }; if ( $@ ) { $sslavailable = 0; } else { $sslavailable = 1; } # Make socket SSL! if ( $sslavailable ) { eval { $socket = POE::Component::SSLify::Client_SSLify( $socket ) }; if ( $@ ) { # Unable to SSLify the socket... } } Mixing Server/Client in the same program Some users have reported success, others failure when they tried to utilize SSLify in both roles. This would require more investigation, so please tread carefully if you need to use it! Blocking mode Normally, Net::SSLeay requires the socket to be in blocking mode for the initial handshake to work. However, various users ( especially ASCENT, thanks! ) have reported success in setting nonblocking mode for clients. In order to enable nonblocking mode, you need to set the subroutine "NONBLOCKING" to a true value in this package. sub POE::Component::SSLify::NONBLOCKING { 1 } use POE::Component::SSLify; This is a global, and an EXPERIMENTAL feature! Please, pretty please report back to me your experience with this. Hopefully someday SSLify will be fully nonblocking, thanks to your help! FUNCTIONS Client_SSLify Accepts a socket, returns a brand new socket SSLified. Optionally accepts SSL context data. my $socket = shift; # get the socket from somewhere $socket = Client_SSLify( $socket ); # the default $socket = Client_SSLify( $socket, $version, $options ); # sets more options for the context $socket = Client_SSLify( $socket, undef, undef, $ctx ); # pass in a custom context If $ctx is defined, SSLify will ignore other args. If $ctx isn't defined, SSLify will create it from the $version + $options parameters. Known versions: * sslv2 * sslv3 * tlsv1 * default By default we use the version: default By default we don't set any options NOTE: The way to have a client socket with proper certificates set up is: my $socket = shift; # get the socket from somewhere my $ctx = SSLify_ContextCreate( 'server.key', 'server.crt' ); $socket = Client_SSLify( $socket, undef, undef, $ctx ); BEWARE: If you passed in a CTX, SSLify will do Net::SSLeay::CTX_free( $ctx ) when the socket is destroyed. This means you cannot reuse contexts! Server_SSLify Accepts a socket, returns a brand new socket SSLified my $socket = shift; # get the socket from somewhere $socket = Server_SSLify( $socket ); NOTE: SSLify_Options must be set first! Furthermore, you can pass in your own $ctx object if you desire. This allows you to set custom parameters per-connection, for example. my $socket = shift; # get the socket from somewhere my $ctx = Net::SSLeay::CTX_new(); # set various options on $ctx as desired $socket = Server_SSLify( $socket, $ctx ); NOTE: You can use SSLify_GetCTX to modify the global, and avoid doing this on every connection if the options are the same... SSLify_Options Accepts the location of the SSL key + certificate files and does it's job Optionally accepts the SSL version + CTX options SSLify_Options( $key, $cert, $version, $options ); Known versions: * sslv2 * sslv3 * tlsv1 * default By default we use the version: default By default we use the options: &Net::SSLeay::OP_ALL SSLify_GetCTX Returns the server-side CTX in case you wanted to play around with it :) If passed in a socket, it will return that socket's $ctx instead of the global. my $ctx = SSLify_GetCTX(); # get the one set via SSLify_Options my $ctx = SSLify_GetCTX( $sslified_sock ); # get the one in the object SSLify_GetCipher Returns the cipher used by the SSLified socket Example: print "SSL Cipher is: " . SSLify_GetCipher( $sslified_sock ) . "\n"; SSLify_GetSocket Returns the actual socket used by the SSLified socket, useful for stuff like getpeername()/getsockname() Example: print "Remote IP is: " . inet_ntoa( ( unpack_sockaddr_in( getpeername( SSLify_GetSocket( $sslified_sock ) ) ) )[1] ) . "\n"; SSLify_ContextCreate Accepts some options, and returns a brand-new SSL context object ( $ctx ) my $ctx = SSLify_ContextCreate(); my $ctx = SSLify_ContextCreate( $key, $cert ); my $ctx = SSLify_ContextCreate( $key, $cert, $version, $options ); Known versions: * sslv2 * sslv3 * tlsv1 * default By default we use the version: default By default we don't set any options By default we don't use the SSL key + certificate files EXPORT Stuffs all of the above functions in @EXPORT_OK so you have to request them directly head1 SUPPORT You can find documentation for this module with the perldoc command. perldoc POE::Component::SSLify Websites * AnnoCPAN: Annotated CPAN documentation * CPAN Ratings * RT: CPAN's request tracker * Search CPAN Bugs Please report any bugs or feature requests to "bug-poe-component-sslify at rt.cpan.org", or through the web interface at .
