		313	=item on_starttls => $cb->($handle, $success[, $error_message])
		314
		315	This callback will be invoked when the TLS/SSL handshake has finished. If

		317	(C<on_stoptls> will not be called in this case).
		318
		319	The session in C<< $handle->{tls} >> can still be examined in this
		320	callback, even when the handshake was not successful.
		321
		322	TLS handshake failures will not cause C<on_error> to be invoked when this
		323	callback is in effect, instead, the error message will be passed to C<on_starttls>.
		324
		325	Without this callback, handshake failures lead to C<on_error> being
		326	called, as normal.
		327
		328	Note that you cannot call C<starttls> right again in this callback. If you
		329	need to do that, start an zero-second timer instead whose callback can

		333
		334	When a SSLv3/TLS shutdown/close notify/EOF is detected and this callback is
		335	set, then it will be invoked after freeing the TLS session. If it is not,
		336	then a TLS shutdown condition will be treated like a normal EOF condition
		337	on the handle.
		338
		339	The session in C<< $handle->{tls} >> can still be examined in this
		340	callback.
		341
		342	This callback will only be called on TLS shutdowns, not when the
		343	underlying handle signals EOF.

		749	Sometimes you know you want to close the socket after writing your data
		750	before it was actually written. One way to do that is to replace your
		751	C<on_drain> handler by a callback that shuts down the socket (and set
		752	C<low_water_mark> to C<0>). This method is a shorthand for just that, and
		753	replaces the C<on_drain> callback with:
		754
		755	sub { shutdown $_[0]{fh}, 1 } # for push_shutdown
		756
		757	This simply shuts down the write side and signals an EOF condition to the
		758	the peer.
		759
		760	You can rely on the normal read queue and C<on_eof> handling
		761	afterwards. This is the cleanest way to close a connection.

		1800	If your TLS server is a pure TLS server (e.g. HTTPS) that only speaks TLS,
		1801	simply connect to it and then create the AnyEvent::Handle with the C<tls>
		1802	parameter:
		1803
		1804	tcp_connect $host, $port, sub {
		1805	my ($fh) = @_;
		1806
		1807	my $handle = new AnyEvent::Handle

		1812	$handle->push_write (...);
		1813	};
		1814
		1815	=item I want to contact a TLS/SSL server, I do care about security.
		1816
		1817	Then you should additionally enable certificate verification, including
		1818	peername verification, if the protocol you use supports it (see
		1819	L<AnyEvent::TLS>, C<verify_peername>).
		1820
		1821	E.g. for HTTPS:
		1822
		1823	tcp_connect $host, $port, sub {
		1824	my ($fh) = @_;
		1825
		1826	my $handle = new AnyEvent::Handle
		1827	fh => $fh,
		1828	peername => $host,
		1829	tls => "connect",
		1830	tls_ctx => { verify => 1, verify_peername => "https" },
		1831	...
		1832
		1833	Note that you must specify the hostname you connected to (or whatever
		1834	"peername" the protocol needs) as the C<peername> argument, otherwise no
		1835	peername verification will be done.
		1836
		1837	The above will use the system-dependent default set of trusted CA
		1838	certificates. If you want to check against a specific CA, add the
		1839	C<ca_file> (or C<ca_cert>) arguments to C<tls_ctx>:
		1840
		1841	tls_ctx => {
		1842	verify => 1,
		1843	verify_peername => "https",
		1844	ca_file => "my-ca-cert.pem",
		1845	},
		1846
		1847	=item I want to create a TLS/SSL server, how do I do that?
		1848
		1849	Well, you first need to get a server certificate and key. You have
		1850	three options: a) ask a CA (buy one, use cacert.org etc.) b) create a
		1851	self-signed certificate (cheap. check the search engine of your choice,
		1852	there are many tutorials on the net) or c) make your own CA (tinyca2 is a
		1853	nice program for that purpose).
		1854
		1855	Then create a file with your private key (in PEM format, see
		1856	L<AnyEvent::TLS>), followed by the certificate (also in PEM format). The
		1857	file should then look like this:
		1858
		1859	-----BEGIN RSA PRIVATE KEY-----
		1860	...header data
		1861	... lots of base64'y-stuff
		1862	-----END RSA PRIVATE KEY-----
		1863
		1864	-----BEGIN CERTIFICATE-----
		1865	... lots of base64'y-stuff
		1866	-----END CERTIFICATE-----
		1867
		1868	The important bits are the "PRIVATE KEY" and "CERTIFICATE" parts. Then
		1869	specify this file as C<cert_file>:
		1870
		1871	tcp_server undef, $port, sub {
		1872	my ($fh) = @_;
		1873
		1874	my $handle = new AnyEvent::Handle
		1875	fh => $fh,
		1876	tls => "accept",
		1877	tls_ctx => { cert_file => "my-server-keycert.pem" },
		1878	...
		1879
		1880	When you have intermediate CA certificates that your clients might not
		1881	know about, just append them to the C<cert_file>.
