How To Install libnettle7 on Ubuntu 20.04
Introduction
In this tutorial we learn how to install libnettle7 on Ubuntu 20.04.
What is libnettle7
libnettle7 is:
Nettle is a cryptographic library that is designed to fit easily in more or less any context: In crypto toolkits for object-oriented languages (C++, Python, Pike, …), in applications like LSH or GNUPG, or even in kernel space.
It tries to solve a problem of providing a common set of cryptographic algorithms for higher-level applications by implementing a context-independent set of cryptographic algorithms. In that light, Nettle doesn’t do any memory allocation or I/O, it simply provides the cryptographic algorithms for the application to use in any environment and in any way it needs.
This package contains the symmetric and one-way cryptographic algorithms. To avoid having this package depend on libgmp, the asymmetric cryptos reside in a separate library, libhogweed. Task: minimal Build-Essential: yes
