Каким образом можно создать SSH-ключ в операционной системе Linux?

To create an SSH key in Linux, the command ssh-keygen is used. It generates a pair of keys: private and public.

Example of creating an RSA key with a length of 4096 bits:

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

Explanations:

• -t rsa — key type (RSA).
• -b 4096 — key length in bits.
• -C — comment, usually an email for identification.

After running, the command will ask where to save the key (default ~/.ssh/id_rsa) and optionally a password to protect the private key.

Result:

• Private key: ~/.ssh/id_rsa
• Public key: ~/.ssh/id_rsa.pub

The public key can be added to the server for passwordless authentication.
