Tresor X

It used to work really fine and was my preferred encryption app, but it is no longer updated and does not work on Intel. One can only regret that developers launch an application on the market, and then no longer update them: I used it for two or three years, and then had to give it up - not without decrypting and reencrypting my files first.

Demo works fine.

Okay, this is not a demo, you have to buy it to use it. For anyone who has bought it, about how much in American dollars is it?

This is what bothers me about this software. With a 256bit AES or 448bit Blowfish program I know no one is going to crack it (not in their life time - based on present technology). But how does Tresor compare tp AES or Blowfish?

I must admit that I didn't like the sound effect on the website - but now it is gone, so people can visit the website without ear protection device! And I have tested Tresor - I was using iCrypt until now, but felt the need for something more developed. Well, I must say I am very pleased, and I have been glad to pay ¢25 for regsitering. First, the developer is very responsive: when I asked him a question (which actually went before the software itself), I received a detailed, precise answer, which was extremely helpful - and showed that the developer is well aware of all issues involved in cryptography. Second, the product seems to be robust and well designed. It also offers some additional features which I find quite useful, for instance the option of destroying a document with several passes (i.e. more than what is offered on the Mac for the secure delete of the trash can). Documents encrypted (I tested it on several types of documents) were restored without any problem. Finally, the developer assures us that there is no backdoor, and since Tresor is developed in Switzerland, I feel quite inclined to trust him: I must admit the fear of having some backdoor is what kept me from using some well-known, American encryption products. I feel that European, lesser-known alternatives are probably a wise choice, and Tresor seems to be a good choice, insofar I am able to ascertain.
