Net::SSLGlue::LWP(3) User Contributed Perl Documentation Net::SSLGlue::LWP(3)NAMENet::SSLGlue::LWP - proper certificate checking for https in LWP
SYNOPSIS
use Net::SSLGlue::LWP SSL_ca_path => ...;
use LWP::Simple;
get( 'https://www....' );
{
local %Net::SSLGlue::LWP::SSLopts = %Net::SSLGlue::LWP::SSLopts;
# switch off verification
$Net::SSLGlue::LWP::SSLopts{SSL_verify_mode} = 0;
# or: set different verification policy, because cert does
# not conform to RFC (wildcards in CN are not allowed for https,
# but some servers do it anyway)
$Net::SSLGlue::LWP::SSLopts{SSL_verifycn_scheme} = {
wildcards_in_cn => 'anywhere',
check_cn => 'always',
};
}
DESCRIPTIONNet::SSLGlue::LWP modifies Net::HTTPS and LWP::Protocol::https so that
Net::HTTPS is forced to use IO::Socket::SSL instead of Crypt::SSLeay,
and that LWP::Protocol::https does proper certificate checking using
the "http" SSL_verify_scheme from IO::Socket::SSL.
Because LWP does not have a mechanism to forward arbitrary parameters
for the construction of the underlying socket these parameters can be
set globally when including the package, or with local settings of the
%Net::SSLGlue::LWP::SSLopts variable.
All of the "SSL_*" parameter from IO::Socket::SSL can be used; the
following parameters are especially useful:
SSL_ca_path, SSL_ca_file
Specifies the path or a file where the CAs used for checking the
certificates are located. This is typically "etc/ssl/certs" on UNIX
systems.
SSL_verify_mode
If set to 0, verification of the certificate will be disabled. By
default it is set to 1 which means that the peer certificate is
checked.
SSL_verifycn_name
Usually the name given as the hostname in the constructor is used
to verify the identity of the certificate. If you want to check the
certificate against another name you can specify it with this
parameter.
