508 | |
517 | |
|
|
518 | For this reason, if the default encoder uses L<JSON::XS>, it will default |
|
|
519 | to not allowing anything but arrays and objects/hashes, at least for the |
|
|
520 | forseeable future (it will change at some point). This might or might not |
|
|
521 | be true for the L<JSON> module, so this might cause a security issue. |

1872 | Checks the input stream for a valid SSL or TLS handshake TLSPaintext |
|
|
1873 | record without consuming anything. Only SSL version 3 or higher |
|
|
1874 | is handled, up to the fictituous protocol 4.x (but both SSL3+ and |
|
|
1875 | SSL2-compatible framing is supported). |
|
|
1876 | |
|
|
1877 | If it detects that the input data is likely TLS, it calls the callback |
|
|
1878 | with a true value for C<$detect> and the (on-wire) TLS version as second |
|
|
1879 | and third argument (C<$major> is C<3>, and C<$minor> is 0..4 for SSL |
|
|
1880 | 3.0, TLS 1.0, 1.1, 1.2 and 1.3, respectively). If it detects the input |
|
|
1881 | to be definitely not TLS, it calls the callback with a false value for |
|
|
1882 | C<$detect>. |
|
|
1883 | |
|
|
1884 | The callback could use this information to decide whether or not to start |
|
|
1885 | TLS negotiation. |
|
|
1886 | |
|
|
1887 | In all cases the data read so far is passed to the following read |
|
|
1888 | handlers. |
|
|
1889 | |
|
|
1890 | Usually you want to use the C<tls_autostart> read type instead. |
|
|
1891 | |
|
|
1892 | If you want to design a protocol that works in the presence of TLS |
|
|
1893 | dtection, make sure that any non-TLS data doesn't start with the octet 22 |
|
|
1894 | (ASCII SYN, 16 hex) or 128-255 (i.e. highest bit set). The checks this |
|
|
1895 | read type does are a bit more strict, but might losen in the future to |
|
|
1896 | accomodate protocol changes. |
|
|
1897 | |
|
|
1898 | This read type does not rely on L<AnyEvent::TLS> (and thus, not on |
|
|
1899 | L<Net::SSLeay>). |

1903 | Tries to detect a valid SSL or TLS handshake. If one is detected, it tries |
|
|
1904 | to start tls by calling C<starttls> with the given arguments. |
|
|
1905 | |
|
|
1906 | In practice, C<$tls> must be C<accept>, or a Net::SSLeay context that has |

|
