ssh-keygen - Command Generator Online

ssh-keygen

`ssh-keygen` is a command-line tool used for generating SSH keys.

Use agent forwarding with an SSH agent (-a)

Specify the number of bits in the key (-b)

Add a comment (such as an email address) (-C)

Specify the hash algorithm used for the key (such as SHA256) (-E)

Specify the filename of the key file (-f)

Specify a new passphrase for the key (-N)

Specify the type of key to create (-t)

Quiet mode (-q)

Example

Generate a default RSA key pair: ssh-keygen
Generate a key pair of a specified type: ssh-keygen -t ed25519
Generate a key pair of a specified length: ssh-keygen -b 4096
Generate a key pair with a specified comment: ssh-keygen -C "johndoe@example.com"
Specify the location of the key: ssh-keygen -f ~/.ssh/my_ssh_key
Generate a password-protected key pair: ssh-keygen -N "password"
Generate a key pair using a specified hash algorithm: ssh-keygen -E sha256
Enable agent forwarding: ssh-keygen -a
Quiet mode: ssh-keygen -q

Note: The parameters can be used in combination. For example, ssh-keygen -t ed25519 -b 4096 -C "johndoe@example.com" generates a key pair of type ed25519, with a length of 4096, and a comment of "johndoe@example.com".
