		305
		306	This callback will be invoked when the TLS/SSL handshake has finished. If

		313	TLS handshake failures will not cause C<on_error> to be invoked when this
		314	callback is in effect, instead, the error message will be passed to C<on_starttls>.
		315
		316	Without this callback, handshake failures lead to C<on_error> being

		318
		319	Note that you cannot call C<starttls> right again in this callback. If you

		328	on the handle.
		329
		330	The session in C<< $handle->{tls} >> can still be examined in this
		331	callback.
		332

		740	Sometimes you know you want to close the socket after writing your data

		1786
		1787	If your TLS server is a pure TLS server (e.g. HTTPS) that only speaks TLS,
		1788	simply connect to it and then create the AnyEvent::Handle with the C<tls>
		1789	parameter:
		1790
		1791	tcp_connect $host, $port, sub {
		1792	my ($fh) = @_;
		1793
		1794	my $handle = new AnyEvent::Handle

		1799	$handle->push_write (...);
		1800	};
		1801
		1802	=item I want to contact a TLS/SSL server, I do care about security.
		1803
		1804	Then you should additionally enable certificate verification, including
		1805	peername verification, if the protocol you use supports it (see
		1806	L<AnyEvent::TLS>, C<verify_peername>).
		1807
		1808	E.g. for HTTPS:
		1809
		1810	tcp_connect $host, $port, sub {
		1811	my ($fh) = @_;
		1812
		1813	my $handle = new AnyEvent::Handle
		1814	fh => $fh,
		1815	peername => $host,
		1816	tls => "connect",
		1817	tls_ctx => { verify => 1, verify_peername => "https" },
		1818	...
		1819
		1820	Note that you must specify the hostname you connected to (or whatever
		1821	"peername" the protocol needs) as the C<peername> argument, otherwise no
		1822	peername verification will be done.
		1823
		1824	The above will use the system-dependent default set of trusted CA
		1825	certificates. If you want to check against a specific CA, add the
		1826	C<ca_file> (or C<ca_cert>) arguments to C<tls_ctx>:
		1827
		1828	tls_ctx => {
		1829	verify => 1,
		1830	verify_peername => "https",
		1831	ca_file => "my-ca-cert.pem",
		1832	},
		1833
		1834	=item I want to create a TLS/SSL server, how do I do that?
		1835
		1836	Well, you first need to get a server certificate and key. You have
		1837	three options: a) ask a CA (buy one, use cacert.org etc.) b) create a
		1838	self-signed certificate (cheap. check the search engine of your choice,
		1839	there are many tutorials on the net) or c) make your own CA (tinyca2 is a
		1840	nice program for that purpose).
		1841
		1842	Then create a file with your private key (in PEM format, see
		1843	L<AnyEvent::TLS>), followed by the certificate (also in PEM format). The
		1844	file should then look like this:
		1845
		1846	-----BEGIN RSA PRIVATE KEY-----
		1847	...header data
		1848	... lots of base64'y-stuff
		1849	-----END RSA PRIVATE KEY-----
		1850
		1851	-----BEGIN CERTIFICATE-----
		1852	... lots of base64'y-stuff
		1853	-----END CERTIFICATE-----
		1854
		1855	The important bits are the "PRIVATE KEY" and "CERTIFICATE" parts. Then
		1856	specify this file as C<cert_file>:
		1857
		1858	tcp_server undef, $port, sub {
		1859	my ($fh) = @_;
		1860
		1861	my $handle = new AnyEvent::Handle
		1862	fh => $fh,
		1863	tls => "accept",
		1864	tls_ctx => { cert_file => "my-server-keycert.pem" },
		1865	...
		1866
		1867	When you have intermediate CA certificates that your clients might not
		1868	know about, just append them to the C<cert_file>.
