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!
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!
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
BUGS
On Win32 platforms SSL support is pretty shaky, please help me out with detailed error descriptions if it happens to you!SEE ALSO
