Cracking LUKS/dm-crypt passphrases
Linux uses dm-crypt in order to provide transparent disk or partition encryption. What are the options in case you need to recover passphrase from such encryption? There are already ready-made tools, but we have also produced and published our own in order to support newer LUKS format/ciphers/hashing.

64 bits ought to be enough for anybody
How quickly can we use brute force to guess a 64-bit number? The short answer is, it all depends on what resources are available. So we’re going to examine this problem starting with the most naive approach and then expand to other techniques involving parallelization. We’ll discuss parallelization at the CPU level…

Comparing Parallel Rust and C++
In this tutorial, we will implement a Rust program that attempts to utilize 100% of the theoretical capacity of three relatively modern, mid-range CPUs. We'll use an existing, highly efficient C++ implementation as a reference point to compare how our Rust program is doing. We start with a simple baseline solution of…
