After more than a decade advocating IPv6, I am amazed to finally have it at home in Copenhagen! Welcome to the future! :-)

Despite the fact that my new Internet provider said they do not have it*....

It is not native IPv6 yet but close enough, and they do assign a full /48 6to4 address range (i.e. many many addresses): 2002:567:x::/48.
I was even able to play successfully with SLAAC (Stateless address autoconfiguration) with success; good riddance IPv4 NAT'ing :-p

* Min Internetudbyder om IPv6, før vi bestilte: "Det er ikke noget vi kan håndtere og bør undlades på jeres pc'er. Hvad jeg forstår er det noget der officielt bliver brugt i Kina og ikke andre steder endnu."

Ah, Java.
So today, I wanted to install Java EE 7 64-bit on a fresh Win8 machine.
The Java EE 64-bit installer fails, then crashes... because it requires... Java.
Nevermind, I install Java 7 JRE 64-bit.
I then re-launch the Java EE 64-bit installer, which crashes again... because it requires a 32-bit version of Java pre-installed. WTF.
I proceed to installing Java 7 JRE 32-bit with online installer, which fails to find the files to download...
Same again with offline installer, which succeeds (yeah... not to mention the crapware bundled with the JRE installer).
The Java EE installer now works, and as I will be working with Tomcat, I do not want Oracle's Glassfish server, but the custom installation that would allow not installing it is "Not Supported".
Sigh...
#java #fail #WTF

Grrr, after Reader and many others, Google is killing yet another great service, this time Latitude, and with less than one month of warning of course. My Google love index is approaching zero... #Latitude
Google Latitude will be retired on August 9th, 2013. Products being retired include Google Latitude in Google Maps for Android, Latitude for iPhone, the Latitude API, the public badge, the iGoogle Gadget, and the Latitude website at maps.google.com/latitude. What does this mean for me?

Cross-platform way of storing hashed passwords, using only built-in functions available in C# .NET 2.0+, Java SE 6+, PHP 5.5+. Based on PBKDF2 with internal SHA-1.

* PHP
http://www.php.net/manual/function.hash-pbkdf2.php

echo hash_pbkdf2('sha1', 'password', 'salt1234', 100000 /iterations/ , 32 * 2 /length/, false /raw_output/);

* C#
http://msdn.microsoft.com/library/yx129kfs.aspx

using (var pbkdf2 = new System.Security.Cryptography.Rfc2898DeriveBytes("password", Encoding.UTF8.GetBytes("salt1234"), iterations: 100000))
{
    Console.WriteLine(BitConverter.ToString(pbkdf2.GetBytes(cb: 32)).Replace("-", String.Empty).ToLowerInvariant());
}

* Java
http://docs.oracle.com/javase/6/docs/api/javax/crypto/SecretKeyFactory.html

java.security.spec.KeySpec keySpec = new javax.crypto.spec.PBEKeySpec("password".toCharArray(), "salt1234".getBytes("UTF-8"), 100000 /iterations/, 32 * 8 /length/);
byte[] bytes = javax.crypto.SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1").generateSecret(keySpec).getEncoded();
StringBuffer result = new StringBuffer();
for (byte b:bytes) result.append(String.format("%02x", b));
System.out.println(result.toString());

#csharp #php #java #cryptography  
Key derivation process [edit]. The PBKDF2 key derivation function has five input parameters: DK = PBKDF2(PRF, Password, Salt, c, dkLen). where: PRF is a pseudorandom function of two parameters with output length hLen (e.g. a keyed HMAC); Password is the master password from which a derived key ...
