How to Generate a Self-Signed Certificate and Private Key using OpenSSL Generating a private key and self-signed certificate can be accomplished in a few simple steps using OpenSSL. We provide here detailed instructions on how to create a private key and self-signed certificate valid for 365 days. Sep 11, 2018 You apply by generating a CSR with a key pair on your server that would, ideally, hold the SSL certificate. The CSR contains crucial organization details which the CA verifies. Generate a CSR and key pair locally on your server. The key pair consists of a public and private key.
From the ssh-keygen manual: ssh-keygen generates, manages and converts authentication keys forssh(1).
Ssh-keygen can create RSA keys for use by SSH protocol version 1and DSA, ECDSA, Ed25519 or RSA keys for use by SSH protocol version 2.From the ssh manual: Public key authentication works as follows: The scheme is based onpublic-key cryptography, using cryptosystems where encryption anddecryption are done using separate keys, and it is unfeasible to derivethe decryption key from the encryption key. Since aes is a, its keys do not come in pairs. Both ends of the communication use the same key.The key generated by ssh-keygen uses for authentication. You do not generate the key used by aes when you use ssh-keygen.

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.

Switch to a working directory
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.

Steam cd key generator. Generate a CSR & Private Key:
openssl req -out CSR.csr -new -newkey rsa:2048 -keyout privatekey.key
openssl req -out CSR.csr -new -newkey rsa:2048 -keyout privatekey.key
Generate Public Key And Private Key Using Openssl Access
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
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: < > ~ ! @ # $ % ^ * / ( ) ?.,&
Note: The following characters can not be accepted: < > ~ ! @ # $ % ^ * / ( ) ?.,&
Field | Example |
---|---|
Country Name | US (2 Letter Code) |
State or Province | New Hampshire (Full State Name) |
Locality | Portsmouth (Full City name) |
Organization | GMO GlobalSign Inc (Entity's Legal Name) |
Organizational Unit | Support (Optional, e.g. a department) |
Common Name | www.globalsign.com (Domain or Entity name) |
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++.
-->To sign an assembly with a strong name, you must have a public/private key pair. This public and private cryptographic key pair is used during compilation to create a strong-named assembly. You can create a key pair using the Strong Name tool (Sn.exe). Key pair files usually have an .snk extension.
Note
In Visual Studio, the C# and Visual Basic project property pages include a Signing tab that enables you to select existing key files or to generate new key files without using Sn.exe. In Visual C++, you can specify the location of an existing key file in the Advanced property page in the Linker section of the Configuration Properties section of the Property Pages window. The use of the AssemblyKeyFileAttribute attribute to identify key file pairs was made obsolete beginning with Visual Studio 2005.

Create a key pair
To create a key pair, at a command prompt, type the following command:
sn –k <file name>
In this command, file name is the name of the output file containing the key pair.
The following example creates a key pair called sgKey.snk.
If you intend to delay sign an assembly and you control the whole key pair (which is unlikely outside test scenarios), you can use the following commands to generate a key pair and then extract the public key from it into a separate file. First, create the key pair:
Next, extract the public key from the key pair and copy it to a separate file:
Generate Key With Openssl
Once you create the key pair, you must put the file where the strong name signing tools can find it.
When signing an assembly with a strong name, the Assembly Linker (Al.exe) looks for the key file relative to the current directory and to the output directory. When using command-line compilers, you can simply copy the key to the current directory containing your code modules.
If you are using an earlier version of Visual Studio that does not have a Signing tab in the project properties, the recommended key file location is the project directory with the file attribute specified as follows:
