NAME

6       Net::SSLGlue::Socket - socket which can be either SSL or plain IP
7       (IPv4/IPv6)
8

SYNOPSIS

10           use Net::SSLGlue::Socket;
11           # SSL right from start
12           my $ssl = Net::SSLGlue::Socket->new(
13               PeerHost => ...,  # IPv4|IPv6 address
14               PeerPort => ...,
15               SSL => 1,
16               SSL_ca_path => ...
17           );
18
19           # SSL through upgrade of plain connection
20           my $plain = Net::SSLGlue::Socket->new(...);
21           $plain->start_SSL( SSL_ca_path => ... );
22           ...
23           $plain->stop_SSL
24

DESCRIPTION

26       First, it is recommended to use IO::Socket::SSL directly instead of
27       this module, since this kind of functionality is available in
28       IO::Socket::SSL since version 1.994.
29
30       Net::SSLGlue::Socket implements a socket which can be either plain or
31       SSL.  If IO::Socket::IP or IO::Socket::INET6 are installed it will also
32       transparently handle IPv6 connections.
33
34       A socket can be either start directly with SSL or it can be start plain
35       and later be upgraded to SSL (because of a STARTTLS commando or
36       similar) and also downgraded again.
37
38       It is possible but not recommended to use the socket in non-blocking
39       mode, because in this case special care must be taken with SSL (see
40       documentation of IO::Socket::SSL).
41
42       Additionally to the usual socket methods the following methods are
43       defined or extended:
44

METHODS

46       new The method "new" of Net::SSLGlue::Socket can have the argument SSL.
47           If this is true the SSL upgrade will be done immediatly. If not set
48           any SSL_* args will still be saved and used at a later start_SSL
49           call.
50
51       start_SSL
52           This will upgrade the plain socket to SSL. See IO::Socket::SSL  for
53           arguments to "start_SSL". Any SSL_* arguments given to new will be
54           applied here too.
55
56       stop_SSL
57           This will downgrade the socket from SSL to plain.
58
59       peer_certificate ...
60           Once the SSL connection is established you can use this method to
61           get information about the certificate. See the IO::Socket::SSL
62           documentation.
63
64       can_read(timeout)
65           This will check for available data. For a plain socket this will
66           only use "select" to check the socket, but for SSL it will check if
67           there are any pending data before trying a select.  Because SSL
68           needs to read the whole frame before decryption can be done, a
69           successful return of can_read is no guarantee that data can be read
70           immediatly, only that new data are either available or in the
71           process of arriving.
