how to make ssh-keygen auto generate

The simplest way to generate a key pair is to run ssh-keygen without arguments. In this case, it will prompt for the file in which to store keys. Here's an example: klar (11:39) ~>ssh-keygen Generating public/private rsa key pair.

I would like to make an automated script that calls ssh-keygen and creates some pub/private keypairs that I will use later on. In principle everything works fine with.... ssh-keygen -b 2048 -t rsa -f /tmp/sshkey -q...except that it asks me for the passphrase that would encrypt the keys. This make -at present- the automation difficult.

 · To generate an SSH key with PuTTYgen, follow these steps: Open the PuTTYgen program. For Type of key to generate, select SSH-2 RSA. Click the Generate button. Move your mouse in the area below the progress bar. When the progress bar is full, PuTTYgen generates your key pair. Type a passphrase in the Key passphrase field.

 · Generate RSA Key with Ssh-keygen. Actually ssh-keygen will create RSA keys by default. So we do not have to specify the algorithm but in order to be sure and provide information we can explicitly specify the RSA key creation. We will use -t option in order to specify the RSA algorithm.

Use the ssh-keygen command to generate a public/private authentication key pair. Authentication keys allow a user to connect to a remote system without supplying a password. Keys must be generated for each user separately. If you generate key pairs as the root user, only the root can use the keys.

 · 4. Your public and private SSH key should now be generated. Open the file manager and navigate to the .ssh directory. You should see two files: id_rsa and 5. Upload the file to the home folder of your remote host (assuming your remote host is running Linux as well). Connect to your remote host via SSH and use the following command to move the public key to the correct ...

You’re looking for a pair of files named something like id_dsa or id_rsa and a matching file with a .pub extension. The .pub file is your public key, and the other file is the corresponding private key. If you don’t have these files (or you don’t even have a .ssh directory), you can create them by running a program called ssh-keygen, which is provided with the SSH package on Linux/macOS ...

 · ssh-keygen -t rsa Step Two—Store the Keys and Passphrase. Once you have entered the Gen Key command, you will get a few more questions: Enter file in which to save the key (/home/ demo /.ssh/id_rsa): You can press enter here, saving the file to the user home (in this case, my example user is called demo). Enter passphrase (empty for no ...

This will generate a key pair for your system. Note: Administrators that have other users connecting to their sshd2 daemon should notify the users of the host-key change. If you do not, the users will receive a warning the next time they connect, because the host key the users have saved on their disk for your server does not match the host key ...

We need to accomplish two steps automatically:. Enter a passphrase.Use the -N flag (void string for this example):. ssh-keygen -t rsa -N '' Overwrite the key file:. Use -f to enter the path (in this example id_rsa) plus a here-string to answer yes to the following question:. ssh-keygen -q -t rsa -N '' …
