You shall now be able to see a new monitor mode listed like m or. We can assume that the name of wireless interface is be sure to use the correct name if it differs from this, then we are going to place the interface in the monitor mode:Īfter this, you need to run iwconfig. If no interface is listed, then it means that your wireless card does not provide support to the monitor mode. You need to begin with listing the wireless interactions that support monitor mode with:

Google for 0192023a7bbd73250516f069df18b500, first hit and bingo! You just broke an MD5 hashed password … BenchmarksĪll Benchmarks were done on an old Windows 7 Laptop (Core2Duo, 2.54GHz, 8GB): SystemVersion current. Just try the following with your favorite password: (MD5 hashMessage: 'admin123') hex. Last but not least: Even “just” one second is much more secure than simply hashing passwords (let’s say with SHA-1 or MD5, especially w/o salts) … those can be broken instantly using rainbow tables. Using a 16 bytes derived key size this still means around 1*10 25 years ( ((2 raisedTo: (16*8)) / 1000000) seconds asDays / 365) to crack the password.Įven if we only assume simple passwords (8 characters, only letters and numbers) we get around 6 years ( (((26+26+10) raisedTo: 8) / 1000000) seconds asDays / 365) … ConclusionĬonfiguring PBKDF2 to use 1 second per check on the deployment platform provides “enough” security for my needs … and the next deployment platform will be faster and use more iterations. But even if the GPU based approach is faster by a factor of let’s say one million this means 1.000.000 passwords per second. Of course the rate of passwords for PBKDF2 on a GPU is much higher than the Smalltalk implementation. On the other hand this also means that an attacker will need about the same time to check the password. That’s no big deal - neither for the user nor for the server (unless you have hundreds of logins per second). So when a user logs on the server needs 1 second to validate the password. My current rule of thumb is to “1 second per hash”: So I configure the hash-function/iterations to consume about 1 second of time on the deployment server. Some settings are using defaults unless otherwise specified: Defaults E.g.: derivedKey := PBKDF2 derivedKeySHA1Password: password salt: salt.

#Wpa2 hash function code#
I’m using this code to store hashed+salted passwords. The only requirement is the Cryptography package. The implementation is directly based on RFC 2898. I just extracted some PBKDF2 code I’m using in a project to it’s own package.
