How To Install sha2 on Fedora 34

sha2 is SHA Implementation Library SHA Implementation Library

Introduction

In this tutorial we learn how to install sha2 on Fedora 34.

What is `sha2`

The library implements the SHA-256, SHA-384, and SHA-512 hash algorithms. The interface is similar to the interface to SHA-1 found in the OpenSSL library. sha2 is a simple program that accepts input from either STDIN or reads one or more files specified on the command line, and then generates the specified hash (either SHA-256, SHA-384, SHA-512, or any combination thereof, including all three at once). sha2 1.0.1 19.fc34 x86_64 29 k sha2-1.0.1-19.fc34.src.rpm fedora SHA Implementation Library http BSD The library implements the SHA-256, SHA-384, and SHA-512 hash algorithms.

We can use yum or dnf to install sha2 on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install sha2.

Install sha2 on Fedora 34 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
Fedora 34 openh264 (From Cisco) - x86_64        1.4 kB/s | 989  B     00:00
Fedora Modular 34 - x86_64                       68 kB/s | 6.5 kB     00:00
Fedora 34 - x86_64 - Updates                    3.5 kB/s | 6.2 kB     00:01
Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
Metadata cache created.

After updating yum database, We can install sha2 using dnf by running the following command:

sudo dnf -y install sha2

Install sha2 on Fedora 34 Using yum

Update yum database with yum using the following command.

sudo yum makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00

Fedora 34 - x86_64 - Updates                    3.5 kB/s | 6.2 kB     00:01
Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
