Keepass Master Password Crack
KeePass uses a custom password derivation process which includes multiple iterations of symmetric encryption with a random key (which then serves as salt), as explained. The default number of iterations is 6000, so that's 12000 AES invocations for processing one password (encryption is done on a 256-bit value, AES uses 128-bit blocks, so there must be two AES invocations at least for each round). With a quad-core recent PC (those with the spiffy ), you should be able to test about 32000 potential passwords per second.
With ten random characters chosen uniformly among the hundred-of-so of characters which can be typed on a keyboard, there are 10 20 potential passwords, and brute force will, on average, try half of them. You're in for 10 20*0. Nigel Kennedy Vivaldi Rapidshare Premium. 5/32000 seconds, also known as 50 million years. But with two PC that's only 25 million years. This assumes that the password derivation process is not flawed in some way. In 'custom password derivation process', the 'custom' is a scary word. Also, the number of iterations is configurable (6000 is only the default value). Die Gilde 2 Renaissance Patch 4.17 Beta.
LastPass is one of the best Password Manager for Windows users, though it comes with the extension, mobile app, and even desktop app support for all the browsers and. Feb 19, 2015. Now, you might consider trying to crack your KeePass database. It's probably a bad idea. KeePass has built-in protection against brute force and cracking attempts, but there are tutorials that try to show you how to do it anyway. However, if your master password or key was strong (and it should be), most.
You are right it takes long time. But don't forget, that you don't need to try every password combinaten. If you hit the correct one you are done. So you don't really need 50million years.
And you have a lot more options than using 2 quadcore PCs. You can use a Amazon Cloud based Cluster and can start 5000 High CPU instances. Of course this is expensive but you don't need to buy 5000 HighEnd Computer so it decrease the price dramaticly. But i don't know how long you will bruteforce that by using a Cluster. And of course you are rigt that is takes long time for a normal PC today.
