How to Generate & Use Private Keys using OpenSSL's Command Line Tool

These commands generate and use private keys in unencrypted binary (not Base64 “PEM”) PKCS#8 format. The PKCS#8 format is used here because it is the most interoperable format when dealing with software that isn't based on OpenSSL.

OpenSSL has a variety of commands that can be used to operate on private key files, some of which are specific to RSA (e.g. openssl rsa and openssl genrsa) or which have other limitations. Here we always use

There are several ways to clone a repository from github. Similar from other providers, such as bitbucket, gitlab, etc.

Mostly, we use

http
ssh

Sample clone commands:

Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

extract ova files from an archive

$ tar -xvf vmName.ova

modify ovf for some invalid tag

$ vi vmName.ovf

	package aead

	import (
	"crypto/aes"
	"encoding/binary"
	"errors"
	"math/big"
	)

	var _mod = big.NewInt(0)

	const forge = require('node-forge');
	forge.options.usePureJavaScript = true;

	class Field {
	static _MOD = [0n, 121n, 126n, 127n, 128n].map(i => 1n << i).reduce(((previousValue, currentValue) => previousValue + currentValue));
	static _INV = [0n, 114n, 121n, 124n, 127n].map(i => 1n << i).reduce(((previousValue, currentValue) => previousValue + currentValue));

	static add(x, y) {
	return x ^ y;
	}
