Using SSH public-key authentication to connect to a remote system is a robust, more secure alternative to logging in with an account password or passphrase. SSH public-key authentication relies on asymmetric cryptographic algorithms that generate a pair of separate keys (a key pair), one 'private' and the other 'public'. You keep the private key a secret and store it on the computer you use to connect to the remote system. Conceivably, you can share the public key with anyone without compromising the private key; you store it on the remote system in a
.ssh/authorized_keys directory.
Before you begin
May 28, 2006 Generating keys for the client (your Mac) This will generate a public/private key pair. Needless to say, the private key (/.ssh/idrsa) should be kept private at all times, and the public key (/.ssh/idrsa.pub) is meant for distribution. Let’s do that right now. In the Number of bits in a generated key box, enter 2048. Click Generate to generate a public/private key pair. As the key is being generated, move the mouse around the blank area as directed. (Optional) Enter a passphrase for the private key in the Key passphrase box and reenter it in the Confirm passphrase box.
To use SSH public-key authentication:
Set up public-key authentication using SSH on a Linux or macOS computer
To set up public-key authentication using SSH on a Linux or macOS computer:
Set up public-key authentication using PuTTY on a Windows 10 or Windows 8.x computer
The PuTTY command-line SSH client, the PuTTYgen key generation utility, the Pageant SSH authentication agent, and the PuTTY SCP and SFTP utilities are packaged together in a Windows installer available under The MIT License for free download from the PuTTY development team.
After installing PuTTY:

Generate ssh key mac terminal. The next time you log into your Windows desktop, Pageant will start automatically, load your private key, and (if applicable) prompt you for the passphrase.

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.
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. Stark state mindtap key generator.
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:
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:
