NAME

DIAGNOSTICS

NAME

Net::SSL − support for Secure Sockets Layer

METHODS

new

Creates a new "Net::SSL" object.

configure

Configures a "Net::SSL" socket for operation.

configure_certs

Sets up a certificate file to use for communicating with on the socket.

connect
die_with_error
get_cipher
get_lwp_object

Walks up the caller stack and looks for something blessed into the "LWP::UserAgent" namespace and returns it. Vaguely deprecated.

get_peer_certificate

Gets the peer certificate from the underlying "Crypt::SSLeay::Conn" object.

get_peer_verify
get_shared_ciphers
getchunk

Attempts to read up to 32KiB of data from the socket. Returns "undef" if nothing was read, otherwise returns the data as a scalar.

getline

Reads one character at a time until a newline is encountered, and returns the line, including the newline. Grossly inefficient.

print

Concatenates the input parameters and writes them to the socket. Does not honour $, nor $/. Returns the number of bytes written.

printf

Performs a "sprintf" of the input parameters (thus, the first parameter must be the format), and writes the result to the socket. Returns the number of bytes written.

proxy

Returns the hostname of an https proxy server, as specified by the "HTTPS_PROXY" environment variable.

proxy_connect_helper

Helps set up a connection through a proxy.

read

Performs a read on the socket and returns the result.

ssl_context
sysread

Is an alias of "read".

timeout

Returns the timeout value of the socket as defined by the implementing class or 60 seconds by default.

blocking

Returns a boolean indicating whether the underlying socket is in blocking mode. By default, Net::SSL sockets are in blocking mode.

    $sock−>blocking(0); # set to non−blocking mode

This method simply calls the underlying "blocking" method of the IO::Socket object.

write

Writes the parameters passed in (thus, a list) to the socket. Returns the number of bytes written.

syswrite

Is an alias of "write".

accept

Not yet implemented. Will die if called.

getc

Not yet implemented. Will die if called.

getlines

Not yet implemented. Will die if called.

ungetc

Not yet implemented. Will die if called.

send_useragent_to_proxy

By default (as of version 2.80 of "Net::SSL" in the 0.54 distribution of Crypt::SSLeay), the user agent string is no longer sent to the proxy (but will continue to be sent to the remote host).

The previous behaviour was of marginal benefit, and could cause fatal errors in certain scenarios (see CPAN bug #4759) and so no longer happens by default.

To reinstate the old behaviour, call "Net::SSL::send_useragent_to_proxy" with a true value (usually 1).

DIAGNOSTICS 

  "no port given for proxy server <proxy>"

A proxy was specified for configuring a socket, but no port number was given. Ensure that the proxy is specified as a host:port pair, such as "proxy.example.com:8086".

  "configure certs failed: <contents of $@>; <contents of $!>"
  "proxy connect failed: <contents of $@>; <contents of $!>"
  "Connect failed: <contents of $@>; <contents of $!>"

During connect().

SEE ALSO
IO::Socket::INET

"Net::SSL" is implemented by subclassing "IO::Socket::INET", hence methods not specifically overridden are defined by that package.

Net::SSLeay

A package that provides a Perl-level interface to the "openssl" secure sockets layer library.
