Vypnutie kontroly platnosti SSL certifikátu

V prípade, že používate self-signed SSL certifikát a potrebujete otestovať nastavenia webservera, kontrolu platnosti certifikátu vypnete nasledovne:

wget

wget -O - --no-check-certificate https://my.hostname.sk

Bez voľby --no-check-certificate request zlyhá na chybe:

wget -O - https://my.hostname.sk
--2012-10-02 22:18:39--  https://my.hostname.sk/
Resolving my.hostname.sk (my.hostname.sk)... 109.74.151.140
Connecting to my.hostname.sk (my.hostname.sk)|109.74.151.140|:443... connected.
ERROR: The certificate of ‘my.hostname.sk’ is not trusted.
ERROR: The certificate of ‘my.hostname.sk’ hasn't got a known issuer.

curl

Pre curl vyzerá voľba obdobne:

curl --insecure https://my.hostname.sk

curl https://my.hostname.sk
curl: (60) SSL certificate problem: self signed certificate
More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

GET

Debugovací nástroj GET z balíka libwww-perl je utilitka napísaná v Perle, fungujú teda rovnaké premenné prostredia ako pre knižnicu OpenSSL v Perle:

file /usr/bin/GET
/usr/bin/GET: symbolic link to `lwp-request'
file /usr/bin/lwp-request
/usr/bin/lwp-request: Perl script, ASCII text executable
PERL_LWP_SSL_VERIFY_HOSTNAME=0 GET -e -S https://my.hostname.sk

Perl

Pre Perl potrebujete trošku poznať vnútornosti OpenSSL knižnice, takže príslušná voľba sa zisťuje ťazšie, ale toto je ona:

use strict;
use warnings;

use WWW::Mechanize;

$ENV{PERL_LWP_SSL_VERIFY_HOSTNAME} = 0;
my $url = '';
my $mech = new WWW::Mechanize;

my $response = $mech->get($url);

print $response->as_string;
