# Nettle-3.10.1

## Introduction to Nettle

The Nettle package contains a low-level cryptographic library that is designed to fit easily in many contexts.

- Download: https://ftpmirror.gnu.org/gnu/nettle/nettle-3.10.1.tar.gz

## Installation of Nettle

Install Nettle by running the following commands:

    ./configure --prefix=/usr --disable-static &&
    make

Now, as the `root` user:

    make install &&
    chmod -v 755 /usr/lib/lib{hogweed,nettle}.so &&
    install -vdm755 /usr/share/doc/nettle-3.10.1 &&
    install -vDm644 nettle.{html,pdf} -t /usr/share/doc/nettle-3.10.1/

## Command Explanations

### Note

Run ./configure --help for a full list of options.

`--disable-static`: This switch prevents installation of static versions of the libraries.

## Contents

Installed Programs: nettle-hash, nettle-lfib-stream, nettle-pbkdf2, pkcs1-conv and sexp-conv
Installed Libraries: libhogweed and libnettle
Installed Directory: /usr/include/nettle and /usr/share/doc/nettle-3.10.1

### Short Descriptions

nettle-hash | calculates a hash value using a specified algorithm
nettle-lfib-stream | outputs a sequence of pseudorandom (non-cryptographic) bytes, using Knuth's lagged fibonacci generator. The stream is useful for testing, but should not be used to generate cryptographic keys or anything else that needs real randomness
nettle-pbkdf2 | is a password-based key derivation function that takes a password or a passphrase as input and returns a strengthened password, which is protected against pre-computation attacks by using salting and other expensive computations.
pkcs1-conv | converts private and public RSA keys from PKCS #1 format to sexp format
sexp-conv | converts an s-expression to a different encoding
