<!-- Code generated from the comments of the SSH struct in helper/communicator/config.go; DO NOT EDIT MANUALLY -->

- `ssh_host` (string) - The address to SSH to. This usually is automatically configured by the
  builder.

- `ssh_port` (int) - The port to connect to SSH. This defaults to `22`.

- `ssh_username` (string) - The username to connect to SSH with. Required if using SSH.

- `ssh_password` (string) - A plaintext password to use to authenticate with SSH.

- `ssh_ciphers` ([]string) - This overrides the value of ciphers supported by default by golang.
  The default value is [
    "aes128-gcm@openssh.com",
    "chacha20-poly1305@openssh.com",
    "aes128-ctr", "aes192-ctr", "aes256-ctr",
  ]
  
  Valid options for ciphers include:
  "aes128-ctr", "aes192-ctr", "aes256-ctr", "aes128-gcm@openssh.com",
  "chacha20-poly1305@openssh.com",
  "arcfour256", "arcfour128", "arcfour", "aes128-cbc", "3des-cbc",

- `ssh_clear_authorized_keys` (bool) - If true, Packer will attempt to remove its temporary key from
  `~/.ssh/authorized_keys` and `/root/.ssh/authorized_keys`. This is a
  mostly cosmetic option, since Packer will delete the temporary private
  key from the host system regardless of whether this is set to true
  (unless the user has set the `-debug` flag). Defaults to "false";
  currently only works on guests with `sed` installed.

- `ssh_key_exchange_algorithms` ([]string) - If set, Packer will override the value of key exchange (kex) altorighms
  supported by default by golang. Acceptable values include:
  "curve25519-sha256@libssh.org", "ecdh-sha2-nistp256",
  "ecdh-sha2-nistp384", "ecdh-sha2-nistp521",
  "diffie-hellman-group14-sha1", and "diffie-hellman-group1-sha1".

- `ssh_certificate_file` (string) - Path to user certificate used to authenticate with SSH.
  The `~` can be used in path and will be expanded to the
  home directory of current user.

- `ssh_pty` (bool) - If `true`, a PTY will be requested for the SSH connection. This defaults
  to `false`.

- `ssh_timeout` (duration string | ex: "1h5m2s") - The time to wait for SSH to become available. Packer uses this to
  determine when the machine has booted so this is usually quite long.
  Example value: `10m`.

- `ssh_disable_agent_forwarding` (bool) - If true, SSH agent forwarding will be disabled. Defaults to `false`.

- `ssh_handshake_attempts` (int) - The number of handshakes to attempt with SSH once it can connect. This
  defaults to `10`.

- `ssh_bastion_host` (string) - A bastion host to use for the actual SSH connection.

- `ssh_bastion_port` (int) - The port of the bastion host. Defaults to `22`.

- `ssh_bastion_agent_auth` (bool) - If `true`, the local SSH agent will be used to authenticate with the
  bastion host. Defaults to `false`.

- `ssh_bastion_username` (string) - The username to connect to the bastion host.

- `ssh_bastion_password` (string) - The password to use to authenticate with the bastion host.

- `ssh_bastion_interactive` (bool) - If `true`, the keyboard-interactive used to authenticate with bastion host.

- `ssh_bastion_private_key_file` (string) - Path to a PEM encoded private key file to use to authenticate with the
  bastion host. The `~` can be used in path and will be expanded to the
  home directory of current user.

- `ssh_bastion_certificate_file` (string) - Path to user certificate used to authenticate with bastion host.
  The `~` can be used in path and will be expanded to the
  home directory of current user.

- `ssh_file_transfer_method` (string) - `scp` or `sftp` - How to transfer files, Secure copy (default) or SSH
  File Transfer Protocol.

- `ssh_proxy_host` (string) - A SOCKS proxy host to use for SSH connection

- `ssh_proxy_port` (int) - A port of the SOCKS proxy. Defaults to `1080`.

- `ssh_proxy_username` (string) - The optional username to authenticate with the proxy server.

- `ssh_proxy_password` (string) - The optional password to use to authenticate with the proxy server.

- `ssh_keep_alive_interval` (duration string | ex: "1h5m2s") - How often to send "keep alive" messages to the server. Set to a negative
  value (`-1s`) to disable. Example value: `10s`. Defaults to `5s`.

- `ssh_read_write_timeout` (duration string | ex: "1h5m2s") - The amount of time to wait for a remote command to end. This might be
  useful if, for example, packer hangs on a connection after a reboot.
  Example: `5m`. Disabled by default.

- `ssh_remote_tunnels` ([]string) - 

- `ssh_local_tunnels` ([]string) -
