In Linux, the ssh-keygen command is used to generate and manage SSH key pairs. Its basic usage is as follows:<\/p>\n

    \n
  1. Open the terminal.<\/li>\n
  2. Please input the following command:<\/li>\n
  3. Generate a new SSH key<\/li>\n
  4. To generate key pairs for specific users, you can use the following command:<\/li>\n
  5. Generate a SSH key at the specified path.<\/li>\n
  6. In this case, \/path\/to\/ssh\/key is the path and file name for generating the key pair.<\/li>\n
  7. Next, the command will prompt you to enter a storage location and file name for the key, which by default will be stored in the user’s .ssh directory with the file names id_rsa (private key) and id_rsa.pub (public key).<\/li>\n
  8. Next, the command will prompt you to enter a password to protect the private key. You have the option to either set a password or leave it blank.<\/li>\n
  9. After completing the steps above, ssh-keygen will generate a pair of keys.<\/li>\n
  10. Your identification information has been stored in \/path\/to\/ssh\/key. Your public key has also been stored in \/path\/to\/ssh\/key.pub. The fingerprint of the key is SHA256:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx user@host. Additionally, the key’s randomart image is displayed above.<\/li>\n
  11. Now, you can deploy the public key id_rsa.pub to the remote server for SSH key authentication.<\/li>\n<\/ol>\n

    Note: When using the ssh-keygen command, you can customize the type, length, encryption algorithm, and other options of the key. You can use the man ssh-keygen command to view a complete list of options and detailed explanations for ssh-keygen.<\/p>\n","protected":false},"excerpt":{"rendered":"
