A 'CSR with only the public key' is the public key itself. And no CSR can be made without signing the content, which requires access to the private key (that's the whole point of it, to avoid CSR forging - plus that is how asymmetric cryptography works). Generating keys using OpenSSL There are two ways of getting private keys into a YubiKey: You can either generate the keys directly on the YubiKey, or generate them outside of the device, and then importing them into the YubiKey. Sep 11, 2018 Certificate signing requests (CSR) are generated with a pair of keys â a public and private key. Only the public key is sent to a Certificate Authority and included in the SSL certificate, and it works together with your private key to encrypt the connection. If you are running Windows, grab the Cygwin package. OpenSSL can generate several kinds of public/private keypairs. RSA is the most common kind of keypair generation. Other popular ways of generating RSA public key / private key pairs include PuTTYgen and ssh-keygen. Run the following OpenSSL command to generate your private key and public certificate. Answer the questions and enter the Common Name when prompted. Openssl req -newkey rsa:2048 -nodes -keyout key.pem -x509 -days 365 -out certificate.pem.

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:
Generate Rsa Key Openssl
sn âk <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:
Openssl Key Pair
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:
