Last week I was invited by Ahmed Hashim, the Egyptian Java User Group (EGJUG) leader for a technical talk about what is coming in Java 7. I was happy to perform a talk in the Faculty of Computers and Informatics (FCI) of Cairo University in front of 60-70 keen Java developers: I presented the key

By design when we open an SSL connection in Java (e.g. through java.net.URL.openConnection(“https://….”)) the JSSE implementation of the SSL protocol performs few validations to ensure the requested host is not fake. This involves validation of the server’s X.509 certificate with the PKIX algorithm and checking the host name agains the certificate subject. If the SSL

Last few nights I was debugging very strange bug. Few months ago we shipped Java applet signing Web forms in the client’s Web browser. It was tested under IE 6, IE 7, Firefox 2, Firefox 3, Opera 9 and Safari 3 for Windows. We tested with Java 5 and Java 6 in Windows and Linux

We use few external libraries (Bouncy Castle Crypto API and few others) and these libraries are above 2 MB in several JAR files. If we were developing server side application,

In one of my last projects I was working on Java applet that needed to digitally sign data forms at the client side in a Web browser. I with my team developed the applet and it did the job well. Unfortunately our customer decided to put multiple instances of the applet in a single Web
