current 2013 bullet proof SSL config

Posted on by mario

Now in December 2013 the best available SSL config with a 4096 bit RSA Key and httpd Apache 2.4.7 with OpenSSL/1.0.1e.

SSLSessionCache shmcb:/opt/apache2/logs/ssl_gcache_data(512000)
SSLOptions +StrictRequire +StdEnvVars -ExportCertData
SSLProtocol -all +TLSv1 +TLSv1.1 +TLSv1.2
SSLCompression Off
SSLHonorCipherOrder On
SSLCipherSuite ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-SHA256:DHE-RSA-AES256-SHA:!LOW:!MD5:!aNULL:!eNULL:!3DES:!EXP:!PSK:!SRP:!DSS

YES Windows XP is no longer supported with this. But for me there is no more need to do so.

ssl test lab result

The SSL Test Lap Test shows a very good result. The Cipher Strength is at 100%. So any browser will use a 256 bit encrypted connection to that server.

Good bye spam!

Posted on by mario

Since the spam increased that much up to 10k spam each week I searched for a solution. It came out that the combination of Akismet and Stop Spammer Registrations Plugin made it possible to have only 1 or 2 spam comments in the queue. I love it!

Good bye de@r spam!

Subversion (svn) 1.8 on Debian 7 wheezy

Posted on by mario

Just installed a brand new debian and than I can’t use my working copies cause the svn version is still 1.6.x
So an upgraded is required!

 

wget http://opensource.wandisco.com/wandisco-debian.gpg -O /tmp/wd-deb.gpg
apt-key add /tmp/wd-deb.gpg
rm /tmp/wd-deb.gpg
sudo nano /etc/apt/sources.list

deb http://opensource.wandisco.com/debian wheezy svn18

So now I can have fun again! Why not git? Cause the company repos are still in svn and I had some troubles with git-svn.

Spam is increasing … alot!

Posted on by mario

Well since the last years the spam comments in this blog have increased.

2009    114
2010    970
2011    3013
2012    4537
2013    12916 and this year is not over yet. US gouverment talked about they took down some large bot nets. I’m not sure they were that successful as they say. How many bot nets might be in public cloud like ämäzön or so? It is hard to guess, but the massive flood of spam comments and even larger flood of spam email has increased. Also the scum mail in Real Life (TM) has increased. D’oh!

__toString() must not throw an exception

__toString() must not throw an exception.

 

If you an exception handler even that seems fail (in itself) with __toString() must not throw an exception. There is no nice safe way to handle it. The easiest solution is to catch that error as well. It might seems to be odd, but on the other hand the exception hanler shall not fail ;)

/**
* String representation of this object
* @return string
*/
public function __toString()
{
try {
return (string) $this->name;
} catch (Exception $exception) {
return '';
}
}
Javascript money format

Posted on  by mario
Number.prototype.moneyformat = function(decPlaces, thouSeparator, decSeparator) {
	var n = this,
	sign = n < 0 ? "-" : "",
	i = parseInt(n = Math.abs(+n || 0).toFixed(decPlaces),10) + "",
	j = (j = i.length) > 3 ? j % 3 : 0;
	return sign + (j ? i.substr(0, j) + thouSeparator : "") + i.substr(j).replace(/(\d{3})(?=\d)/g, "$1" + thouSeparator) + (decPlaces ? decSeparator + Math.abs(n - i).toFixed(decPlaces).slice(2) : "");
};
usage:
var myMoney=3543.75873;
var formatedMoney = myMoney.moneyformat(2,'.',',') + ' EUR';
