Using OAuth 2.0 with Talend to Access Google APIs

This tutorial deals with a reasonably complicated process and the Talend DI stuff is arguably the simple bit. As this is the case, I will not be going through each of the steps in as much detail as some of the other tutorials. It is assumed that if this functionality is required, that most of the Talend DI basics will have been mastered, or at least understood.

A Talend "Connect By" Example

Out of the box, Talend's Data Integration components cover many scenarios. However, there are some where there simply isn't a component that will do the job. In situations like that you can search for bespoke components that people have built, or maybe even build one yourself. But the problem is that these components are not supported and will not be guaranteed to be upgraded when the version you are using is upgraded. A good way to get around this is to create a child job that provides the functionality you require.

The Vigenère Cipher

The Vigenère cipher is an encryption algorithm that was originally described by Giovan Battista Bellaso in 1553. However it was misattributed to the French diplomat, cryptographer, translator and alchemist Blaise de Vigenère in the 19th century and the name has stuck. It is basically a method of encrypting text using a repeating sequence of Caesar ciphers based on a pass phrase. Although this is an old and comparatively easy cipher, the Vigenère cipher can still be pretty secure depending on its pass phrase length.
