OpenSSL loading openssl.cnf

Feb 8th

Posted by editor in ASP.Net

since the openssl.cnf path is hardcoded in binaries. to alter it on windows set environmental variable (as written):

OPENSSLDIR=C:\PATH\TO\OpenSSL\bin
OPENSSL_CONF=C:\PATH\TO\OpenSSL\bin\openssl.cnf

OPENSSL_CONF doesn’t work without OPENSSLDIR even if it is set.

settings these options will allow you to use your custom configuration files when creating certificates.

batch file i use to create certificate

GenCERT.bat [save this file to OpenSSL bin directory]

@echo off 

md %1

openssl genrsa -des3 -out %1/%1.key 1024

openssl req -new -key %1/%1.key -out %1/%1.csr

copy %1/%1.key %1/%1.key.org

openssl rsa -in %1/%1.key.org -out %1/%1.key

openssl x509 -req -days 365 -in %1/%1.csr -signkey %1/%1.key -out %1/%1.crt

openssl x509 -outform der -in %1/%1.crt -out %1/%1.der

Sample

:: Start command line and cd to C:\PATH\TO\OpenSSL\bin
::
:: usage: GenCERT.bat domain.com
::

GenCERT.bat teknober.com

Batch file I use to create SSL certificate for Web etc server

GenPEM.bat [save this file to OpenSSL bin directory] 

@echo off

mkdir %1

openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout %1/%1.pem -out %1/%1.pem -config "%1/%1.cfg"

Sample

:: Start command line and cd to C:\PATH\TO\OpenSSL\bin
::
:: usage: GenPEM.bat domain.com
::

GenPEM.bat teknober.com

for sample ssl configuration file see the bottom of the page: http://www.openssl.org/docs/apps/ca.html

HTML remove cookies from static files, images etc

Mar 24th

Posted by editor in ASP.Net

If you have not configured your application and server, it might send them to browser with cookie information.

that’s costing you as extra traffic and slow load times.

<FilesMatch "\.(css|js|jpg|jpeg|png|gif)$">
    <IfModule mod_headers.c>
        Header set cookie ""
    </IfModule>
</FilesMatch>

HTML Reduce time on page load using performance images

Mar 24th

Posted by editor in ASP.Net

used this method while ago when i was working for one of those websites in top 10 the purpose was to reduce the loading time of the page and improve the parallel download

$(document).ready(function() {
    /* apply performance image */
    $.each($('img'), function(k, v) {
        var src = $(v).attr('src');

        if (src.indexOf('#') >= 0) {
            src = src.split('#');
            $(v).attr('src', src[1]);
        }

    });
});

the trick is simple. host a 1×1.gif image or don’t. up to you and separate the actual image path with ‘#’ and when the dom is ready start replacing them with original path.

make sure your images cachable.
