How To Install argon2 on CentOS 7
Introduction
In this tutorial we learn how to install argon2 on CentOS 7.
What is argon2
Argon2 is a password-hashing function that summarizes the state of the art in the design of memory-hard functions and can be used to hash passwords for credential storage, key derivation, or other applications. It has a simple design aimed at the highest memory filling rate and effective use of multiple computing units, while still providing defense against tradeoff attacks (by exploiting the cache and memory organization of the recent processors). Argon2 has three variants * Argon2d is faster and uses data-depending memory access, which makes it highly resistant against GPU cracking attacks and suitable for applications with no threats from side-channel timing attacks (eg. cryptocurrencies). * Argon2i instead uses data-independent memory access, which is preferred for password hashing and password-based key derivation, but it is slower as it makes more passes over the memory to protect from tradeoff attacks. * Argon2id is a hybrid of Argon2i and Argon2d, using a combination of data-depending and data-independent memory accesses, which gives some of Argon2i’s resistance to side-channel cache timing attacks and much of Argon2d’s resistance to GPU cracking attacks.
We can use yum or dnf to install argon2 on CentOS 7. In this tutorial we discuss both methods but you only need to choose one of method to install argon2.
Install argon2 on CentOS 7 Using yum
Update yum database with yum using the following command.
sudo yum makecache
After updating yum database, We can install argon2 using yum by running the following command:
sudo yum -y install argon2
Install argon2 on CentOS 7 Using dnf
If you don’t have dnf installed you can install DNF on CentOS 7 first.
Update yum database with dnf using the following command.
sudo dnf makecache
After updating yum database, We can install argon2 using dnf by running the following command:
sudo dnf -y install argon2
How To Uninstall argon2 on CentOS 7
To uninstall only the argon2 package we can use the following command:
sudo dnf remove argon2
