![]() Along with the worry of backdoors within the software, there has been several recent cases of severe bugs in the secure software, and which can comprise anything that has been previous kept secure. It has thus been a key target for many defence organisations with a whole range of conspiracy theories around the presence of backdoors in the cryptography software, and where defence agencies have spied on their adversaries. While many defence mechanisms in security have been fairly easy to overcome, cryptography – the process of encrypting and decrypting using electronic keys – has been seen as one of the most difficult defence mechanisms to overcome. In this way not even a man-in-the-middle can read the communications, and the encryption key only resides with those who have rights to access it. The natural step forward, though, is to encrypt the actual data before it is transmitted, and when it is stored. When not perfect, and open to a man-in-the-middle attack, it is a vast improvement to communicating where anyway how can sniff the network packets can read (and change) the communications. Most of the protocols used on the Internet are clear-text ones, such as HTTP, Telnet, FTP, and so on, but increasing we are encrypting our communications (such as with HTTPS, SSH and FTPS), where an extra layer of security (SSL) is added to make it difficult for intruders to read and change our communications. The ability for defence agencies to read secret communications and messages gives them a massive advantage over their adversaries, and is the core of many defence strategies. Well, in the world of cryptography, this is roughly what happened with TrueCrypt. And, finally, that they were shutting down all their plants and burning of all their designs, so that no-one could use them. To add to this they had limited the performance of it so that it was almost unusable, and that car users should go and purchase a Mercedes Benz instead. ![]() Imagine the headlines, if, after a full review of the safety of their cars, that BMW announced that they were releasing a new car that had safety warning messages all over it, and that it was the last car they would ever be building.
