Extract a Mac OSX Catalina user's password hash as a hashcat-compatible string
#!/usr/bin/env python3
"""
Mac OSX Catalina User Password Hash Extractor
Extracts a user's password hash as a hashcat-compatible string.
Mac OSX Catalina (10.15) uses a salted SHA-512 PBKDF2 for storing user passwords
(hashcat type 7100), and it's saved in an annoying binary-plist-nested-inside-xml-plist
format, so previously reported methods for extracting the hash don't work.

Software Transactional Memory in C++: Pure Functional Approach (tutorial)

Software Transactional Memory in C++: pure functional approach (Tutorial)

In this article I’ll tell you about my pure functional library for Software Transactional Memory (STM) that I’ve built in C++. I adopted some advanced functional programming concepts that make it composable and convenient to use. Its implementation is rather small and robust, which differentiates the library from competitors. Let’s discuss what STM is and how to use it.

Make DKMS sign kernel modules on installation, with full script support and somewhat distro independent

On systems with UEFI Secure Boot enabled, recent Linux kernels will only load signed modules, so it's about time DKMS grew the capability to sign modules it's building.

These scripts are extended and scriptified variants of https://computerlinguist.org/make-dkms-sign-kernel-modules-for-secure-boot-on-ubuntu-1604.html and https://askubuntu.com/questions/760671/could-not-load-vboxdrv-after-upgrade-to-ubuntu-16-04-and-i-want-to-keep-secur/768310#768310 and add some error checking, a passphrase around your signing key, and support for compressed modules.

dkms-sign-module is a wrapper for the more generic sign-modules which can also be used outside of DKMS.

Installation

  1. Create a directory under /root, say /root/module-signing, put the three scripts below in there and make them executable: chmod u+x one-time-setup sign-modules dkms-sign-module

Story: Writing Scripts with Go

Story: Writing Scripts with Go

This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.

Why Go is good for scripting?

While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.
