Sep 12, 2014 This section covers OpenSSL commands that are related to generating CSRs (and private keys, if they do not already exist). CSRs can be used to request SSL certificates from a certificate authority. Keep in mind that you may add the CSR information non-interactively with the -subj option, mentioned in the previous section. Apr 19, 2019 The OpenSSH tools include the SCP and SFTP utilities to make transferring keys completely secure. In order to properly configure a Windows client for authenticating via SSH keys, the public key (.PUB) file must be transferred to the client device's.ssh directory and stored in the authorizedkeys text file. The openssl req command from the answer by @Tom H is correct to create a self-signed certificate in server.cert incl. A password-less RSA private key in server.key. Openssl req -nodes -new -x509 -keyout server.key -out server.cert Here is how it works. Omitting -des3 as in the answer by @MadHatter is not enough in this case to create a private key without passphrase.

Generate CSR - OpenSSL

Introduction

This article provides step-by-step instructions for generating a Certificate Signing Request (CSR) in OpenSSL. This is most commonly required for web servers such as Apache HTTP Server and NGINX.

Dec 08, 2017  OpenSSL is descended from the SSLeay library developed by Eric A. Young and Tim J. The OpenSSL toolkit is licensed under a dual-license (the OpenSSL license plus the SSLeay license), which means that you are free to get and use it for commercial and non-commercial purposes as long as you fulfill the conditions of both licenses. Uncompress it anywhere you like and start it by double-clicking the openssl.exe executable in the bin folder. If you create files with OpenSSL, they will appear in the bin directory by default. To create a self-signed SSL certificate, you first need a key. Create it like this: genrsa -des3 -out server.key 4096. Being an open-source tool, OpenSSL is available for Windows, Linux, macOS, Solaris, QNX and most of major operating systems. With its core library written in C programming language, OpenSSL commands can be used to perform hundreds of functions ranging from the CSR generation to converting certificate formats. While Encrypting a File with a Password from the Command Line using OpenSSL is very useful in its own right, the real power of the OpenSSL library is its ability to support the use of public key cryptograph for encrypting or validating data in an unattended manner (where the password is not required to encrypt) is done with public keys.

GNU/Linux & Mac OS X users:
Open a terminal and browse to a folder where you would like to generate your keypair

Windows Users:
Navigate to your OpenSSL 'bin' directory and open a command prompt in the same location.

Generate a CSR & Private Key:
openssl req -out CSR.csr -new -newkey rsa:2048 -keyout privatekey.key

To generate a 4096-bit CSR you can replace the rsa:2048 syntax with rsa:4096 as shown below.
openssl req -out CSR.csr -new -newkey rsa:4096 -keyout privatekey.key

Note: You will be prompted to enter a password in order to proceed. Keep this password as you will need it to use the Certificate.

Fill out the following fields as prompted:
Note: The following characters can not be accepted: < > ~ ! @ # $ % ^ * / ( ) ?.,&

You should now have a Private Key (privatekey.key) which should stay on your computer, and a Certificate Signing Request (CSR.csr), which can be submitted to GlobalSign to sign your public key. Each of these files can be viewed in a plain text editor such as Notepad, TextEdit, Vi, Nano, and Notepad++.
