		321
		322	Note that you cannot call C<starttls> right again in this callback. If you

		333	The session in C<< $handle->{tls} >> can still be examined in this

		1789
		1790	If your TLS server is a pure TLS server (e.g. HTTPS) that only speaks TLS,
		1791	simply connect to it and then create the AnyEvent::Handle with the C<tls>
		1792	parameter:
		1793
		1794	tcp_connect $host, $port, sub {
		1795	my ($fh) = @_;
		1796
		1797	my $handle = new AnyEvent::Handle

		1802	$handle->push_write (...);
		1803	};
		1804
		1805	=item I want to contact a TLS/SSL server, I do care about security.
		1806
		1807	Then you should additionally enable certificate verification, including
		1808	peername verification, if the protocol you use supports it (see
		1809	L<AnyEvent::TLS>, C<verify_peername>).
		1810
		1811	E.g. for HTTPS:
		1812
		1813	tcp_connect $host, $port, sub {
		1814	my ($fh) = @_;
		1815
		1816	my $handle = new AnyEvent::Handle
		1817	fh => $fh,
		1818	peername => $host,
		1819	tls => "connect",
		1820	tls_ctx => { verify => 1, verify_peername => "https" },
		1821	...
		1822
		1823	Note that you must specify the hostname you connected to (or whatever
		1824	"peername" the protocol needs) as the C<peername> argument, otherwise no
		1825	peername verification will be done.
		1826
		1827	The above will use the system-dependent default set of trusted CA
		1828	certificates. If you want to check against a specific CA, add the
		1829	C<ca_file> (or C<ca_cert>) arguments to C<tls_ctx>:
		1830
		1831	tls_ctx => {
		1832	verify => 1,
		1833	verify_peername => "https",
		1834	ca_file => "my-ca-cert.pem",
		1835	},
		1836
		1837	=item I want to create a TLS/SSL server, how do I do that?
		1838
		1839	Well, you first need to get a server certificate and key. You have
		1840	three options: a) ask a CA (buy one, use cacert.org etc.) b) create a
		1841	self-signed certificate (cheap. check the search engine of your choice,
		1842	there are many tutorials on the net) or c) make your own CA (tinyca2 is a
		1843	nice program for that purpose).
		1844
		1845	Then create a file with your private key (in PEM format, see
		1846	L<AnyEvent::TLS>), followed by the certificate (also in PEM format). The
		1847	file should then look like this:
		1848
		1849	-----BEGIN RSA PRIVATE KEY-----
		1850	...header data
		1851	... lots of base64'y-stuff
		1852	-----END RSA PRIVATE KEY-----
		1853
		1854	-----BEGIN CERTIFICATE-----
		1855	... lots of base64'y-stuff
		1856	-----END CERTIFICATE-----
		1857
		1858	The important bits are the "PRIVATE KEY" and "CERTIFICATE" parts. Then
		1859	specify this file as C<cert_file>:
		1860
		1861	tcp_server undef, $port, sub {
		1862	my ($fh) = @_;
		1863
		1864	my $handle = new AnyEvent::Handle
		1865	fh => $fh,
		1866	tls => "accept",
		1867	tls_ctx => { cert_file => "my-server-keycert.pem" },
		1868	...
		1869
		1870	When you have intermediate CA certificates that your clients might not
		1871	know about, just append them to the C<cert_file>.
