I finally added results for PHP 8.4 to my PHP Hashes overview. It generates #hashes for all hash algorithms available in #PHP and shows you how long it took and what the output will look like. Great to compare different algos against each other.

Flagg and I have published our write up on how we solved the $1,000 Holiday #Puzzle hosted by #hashkiller. A shout out to #Hashes and #freeroute from #HK for putting this on.

This puzzle was unique, and at times gave us a run for our money, but persistence and teamwork ultimately paid off.

Good Essay on the History of Bad Password Policies

Stuart Schechter makes some good points on the history of bad password policies:

Rainbow tables for LM #hashes are provided for f#ree by the #developers By default, Ophcrack is #BundledDonations with tables that allow it to crack passwords no longer than 14 characters using only alphanumeric characters. Available for free download are four #WindowsXP tables and four #WindowsVista tables.

It can import hashes from a variety of formats, including dumping directly from the #SAM files of Windows, and can be run via the #commandline or using the program’s #gui

It is mind-blowing that large linear systems show up in the methodology for construction of perfect #hashes and that "randomization" (effectively simple #montecarlo) was used to come up with hashing functions for fixed sets. The number of use cases of #linearalgebra is unreal.

@Juro With #single-#use #cryptographic #hashes, we could still enable somewhat strong #anonymity together with strong human id #verification.

Learning from India’s Aadhar system, it is clear that a single #token isn’t good enough.

Perhaps something similar to blockchain, where you can mine some tokens that identify you. And you can throw away like wallets to escape tracking when you need to.
