We take a look at how link rot risks turning every website into an unreachable island—locking crucial information away behind a plethora of broken links—and some of the security concerns that may arise as a result.

Currently I’m analyzing the process of entropy generation of a Linux 64-bit kernel during system startup (for educational purpose). The system is hosted as/on a (64 bit) virtual machine (Xen domU). For a deep analysis, I’m tracking the sta… Continue reading Linux ‘add_interrupt_randomness’ implementation – low entropy contribution by cycles and jiffies?
I want to use zxcvbn-c but it gives the entropy number, not score like the javascript library does. How do I convert entropy number to a score? (0 to 4)
The zxcvbn blog/source mentions that the score is related to estimated … Continue reading How to convert zxcvbn entropy to score
In Teamviewer, I am using “secure (8 characters)” passwords that are changed daily. I noticed that the password is always 4 numbers and 4 lower case letters, with random positions.
I might be naive, but isn’t that less secur… Continue reading What is the benefit with passwords that are always 50% numbers and 50% letters?
Can the process of generating a password based on the transformation of random 3D data into a 2D data chain have better entropy than other methods of generating 2D random data chains?
Twitter is kind of a crazy place. World leaders doing verbal battle, hashtags that rise and fall along with the social climate, and a never ending barrage of cat pictures all make for a tumultuous stream of consciousness that runs 24/7. What exactly we’re supposed to do with this information is still up to debate, as Twitter has yet to turn it into a profitable service after over a decade of operation. Still, it’s a grand experiment that offers a rare glimpse into the human hive-mind for anyone brave enough to dive in.

For a while now I have been interested in the passphrase concept as a potentially more secure replacement for classical passwords. My interest stemmed from a gut feeling that passphrases would be of a lower entropy than passwords given the… Continue reading Passphrase vs. password entropy
I have been trying to find information on this. But I haven’t found anything online.
When you use the password manager on mac, it can provide “memorable” passwords.
For example pick3″enigma. (You choose the number of charac… Continue reading Entropy on native memorable password on macosX keychain

Many keys are generated from passwords or passphrases. A system that
