Random Primes Generation

2023-01-16 | #cryptography #number-theory

Generating random primes and testing their primality is essential for many cryptographic algorithms. In this post, we’ll explore methods for generating and testing prime numbers. Last modification: 2023-08-01 What is this about We want to develop an algorithm that generates a prime in the range [2^(k-1), 2^k - 1], with k the number of bits required to represent the prime.

Experiments with Btrfs RAID1

2022-02-02 | #btrfs #system

RAID1 is a data replication technique that stores two copies of data on two different disks, providing fault tolerance and high availability in case one of the disks fails. With btrfs, you can create a RAID1 array by combining two or more devices.
