No. It is used for generating primes (/etc/ssh/moduli) for DH key exchange. It is not used in any way for generating SSH keys. How to generate and test the moduli file is explained in separate chapter MODULI GENERATION of manual page for ssh-keygen.
Best Keygen For Mac
The ssh-keygen command allows you to generate several key types and sizes that use varying algorithms. Firstly, you should confirm which variation your hosting platform, service, or other party recommends before creating your access credentials.
The host keys are usually automatically generated when an SSH server is installed. They can be regenerated at any time. However, if host keys are changed, clients may warn about changed keys. Changed keys are also reported when someone tries to perform a man-in-the-middle attack. Thus it is not advisable to train your users to blindly accept them. Changing the keys is thus either best done using an SSH key management tool that also changes them on clients, or using certificates.
Many modern general-purpose CPUs also have hardware random number generators. This helps a lot with this problem. The best practice is to collect some entropy in other ways, still keep it in a random seed file, and mix in some entropy from the hardware random number generator. This way, even if one of them is compromised somehow, the other source of randomness should keep the keys secure.
An SSH key consists of a pair of files. One is the private key, which should never be shared with anyone. The other is the public key. The other file is a public key which allows you to log into the containers and VMs you provision. When you generate the keys, you will use ssh-keygen to store the keys in a safe location so you can bypass the login prompt when connecting to your instances.
When you're prompted to "Enter a file in which to save the key", you can press Enter to accept the default file location. Please note that if you created SSH keys previously, ssh-keygen may ask you to rewrite another key, in which case we recommend creating a custom-named SSH key. To do so, type the default file location and replace id_ssh_keyname with your custom key name.
OpenSSH is the gold standard set of tools for SSH management and, just like the Windows version, the ssh-keygen tool remains the best way to generate new SSH keys on Mac or Linux computers.
Apps by Synium Software - the best software for Mac and iPhone made in Germany. It goes without saying that our latest applications work perfectly with macOS Monterey and iOS 15.We develop applications for Mac and iPhone/iPad exclusively, therefore taking full advantage of the latest technologies offered by macOS and iOS.
Users that need to run Windows apps on their Mac are still best suited running Parallels Desktop over other alternatives. The latest version of the popular software is the best yet, with support for Windows 11, macOS Monterey, and improved performance on Apple M1 Macs. If you're an engineering student that needs to run Windows apps like AutoCAD on a Mac, this is one of the best products you can buy for school.
In addition to the compatibility upgrades, Parallels Desktop 17 also improves graphics performance across the board, especially in OpenGL games. The added convenience of Coherence Mode and Parallels Toolbox for Mac and Windows make this the best package for running Windows and Mac apps side by side. If you're interested in running Windows on Chrome OS, Parallels Desktop can help with that too.
Your goal is to make room for your Mac, not to install a number of third-party utilities that eat up more storage. Ideally, the best cleaner app is cleaning-focused, meaning it should aim to help users remove unneeded files and applications.
In general, MacBooster is a nice app that aims to clean and speed up a Mac machine. Its features are a combination of what CleanMyMac and Gemini offer, and even go beyond. However, choosing the best Mac cleaner software is not simply a game of comparing the number of features. Personally, I still prefer the user experience of CleanMyMac and Gemini, and recommend them because they are more lightweight in nature, as well as the way MacPaw markets their products.

Logging into remote systems with SSH implementations is secure by default -- but those connections are secured only in that they use the TLS protocol to encrypt network protocol exchanges. SSH can be made even more secure by using it to authenticate communicating hosts through the exchange of public keys -- keys that are created using the ssh-keygen command.
GUI versions of SSH usually include the same functionality as the command-line versions. For example, the PuTTYgen program is a GUI version of ssh-keygen for use with PuTTY, a GUI implementation of SSH for Windows. However, modern OSes, including Windows 10 and later, Linux and macOS, include command-line versions of the OpenSSH implementation of SSH.
SSH can be used without a prior exchange of public key pairs, and those uses can be reasonably secure. The best approach for securely authenticating SSH sessions, however, is to create a public key pair for the local computer and copy the public key file to the remote SSH server. Only a user with authenticated permission should be able to copy files to the server. If local users do not have sufficient permission, they can request that a system administrator of the remote host copy the files for them.
The procedures outlined in this tutorial are best applied to individual clients and servers and to demonstrate how SSH keys can be generated and used. Centralized key management systems are preferred for more general use in large organizations where many different users need to be accredited for access to many different servers. Those key management systems are able to automate the processes explained here, however.
The best security practice for SSH calls for the user to copy that fingerprint and authenticate it against the public key of the remote server. In practice, this step is often skipped when the user is confident that the remote server is known to be a trusted server. Once the user accepts the authenticity of the remote server, that server and its fingerprint are added to the known hosts file, and subsequent connections can be made directly.
This ad hoc approach can be adequately secure when the user is connecting to a server inside a protected network, but it can be riskier for connecting to other remote servers. This is where ssh-keygen can streamline the exchange of public key authentication.
The ssh-keygen command is a component of most SSH implementations used to generate a public key pair for use when authenticating with a remote server. In the typical use case, users generate a new public key and then copy their public key to the server using SSH and their login credentials for the remote server.
Secure Shell (SSH) keys are used on modern networks for computers to identify each other, and to grant secure access from one computer on a network to another. The basic was SSH runs is with keys, you create SSH keys in Mac OS X using the ssh-keygen command in Terminal.
