As is every good development :) Passev is delayed. The crypthographic part is taking me more time than expected, as I want to be sure I'm not leaving any security hole. Due to this, Passev launch is going to be delayed about two weeks, so the new release date will be July 15. Sorry for the inconvenience!

Last week I told you about how PassEv will ensure confidentiality by using a shared session key. Today I'm going to talk about how the program will encrypt the local file containing our passwords, or the PassStore, as I'll call it from now on.

A suitable algorithm to  encrypt the data should combine some features: it has to be impossible to crack in a decent time and has to be quick enough to be used so the user hasn't got to wait 15 minutes till the encryption is done. After studying "modern" algorithms, I have decided to use AES, which is a small, fast, hard to crack encryption standard and is suitable for a wide range of devices or applications. It has been determined as the best compromise between a combination of security, performance, efficiency, ease of implementation and flexibility.

128 bit AES offers a total of 3.4 x 10^38 individual keys. It is estimated that if an AES key generator were able to discover 1 AES key per second, it would take 149 thousand-billion (149 trillion) years to crack a single 128 bit AES key.Currently, the technology is not available.

Passev is planned to be released the 1^st of July. Stay tunned if you want to betatest it!
