POE::Component::SSLify - Makes using SSL in the world of POE easy!
# 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...
# !!! 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...
Makes SSL use in POE a breeze!
This component represents the standard way to do SSL in POE.
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.
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...
}
}
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!
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!
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!
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...
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
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
Returns the cipher used by the SSLified socket
Example:
print "SSL Cipher is: " . SSLify_GetCipher( $sslified_sock ) . "\n";
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";
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
Stuffs all of the above functions in @EXPORT_OK so you have to request them directly

Original code is entirely Rocco Caputo ( Creator of POE ) -> I simply
packaged up the code into something everyone could use and accepted the burden
of maintaining it :)
From the PoCo::Client::HTTP code =]
# TODO - This code should probably become a POE::Kernel method,
# seeing as it's rather baroque and potentially useful in a number
# of places.
