# salt.states.ssh_auth

## Control of entries in SSH authorized_key files

The information stored in a user's SSH authorized key file can be easily controlled via the ssh_auth state. Defaults can be set by the enc, options, and comment keys. These defaults can be overridden by including them in the name.

Since the YAML specification limits the length of simple keys to 1024 characters, and since SSH keys are often longer than that, you may have to use a YAML 'explicit key', as demonstrated in the second example below.

salt.states.ssh_auth.absent(name, user, enc='ssh-rsa', comment='', source='', options=None, config='.ssh/authorized_keys', fingerprint_hash_type=None)

  Verifies that the specified SSH key is absent

  name

    The SSH key to manage

  user

    The user who owns the SSH authorized keys file to modify

  enc

    Defines what type of key is being used, can be ed25519, ecdsa, ssh-rsa, ssh-dss or any other type as of openssh server version 8.7.

  comment

    The comment to be placed with the SSH public key

  options

    The options passed to the key, pass a list object

  source

    The source file for the key(s). Can contain any number of public keys, in standard "authorized_keys" format. If this is set, comment, enc and options will be ignored.

    Added in version 2015.8.0.

  config

    The location of the authorized keys file relative to the user's home directory, defaults to ".ssh/authorized_keys". Token expansion %u and %h for username and home path supported.

  fingerprint_hash_type

    The public key fingerprint hash type that the public key fingerprint was originally hashed with. This defaults to `sha256` if not specified.

    Added in version 2016.11.7.

salt.states.ssh_auth.manage(name, ssh_keys, user, enc='ssh-rsa', comment='', source='', options=None, config='.ssh/authorized_keys', fingerprint_hash_type=None, **kwargs)

  Added in version 3000.

  Ensures that only the specified ssh_keys are present for the specified user

  ssh_keys

    The SSH key to manage

  user

    The user who owns the SSH authorized keys file to modify

  enc

    Defines what type of key is being used, can be ed25519, ecdsa, ssh-rsa, ssh-dss or any other type as of openssh server version 8.7.

  comment

    The comment to be placed with the SSH public key

  source

    The source file for the key(s). Can contain any number of public keys, in standard "authorized_keys" format. If this is set, comment and enc will be ignored.

  Note

  The source file must contain keys in the format `<enc> <key> <comment>`. If you have generated a keypair using PuTTYgen, then you will need to do the following to retrieve an OpenSSH-compatible public key.

  1. In PuTTYgen, click `Load`, and select the private key file (not the public key), and click `Open`.

  2. Copy the public key from the box labeled `Public key for pasting into OpenSSH authorized_keys file`.

  3. Paste it into a new file.

  options

    The options passed to the keys, pass a list object

  config

    The location of the authorized keys file relative to the user's home directory, defaults to ".ssh/authorized_keys". Token expansion %u and %h for username and home path supported.

  fingerprint_hash_type

    The public key fingerprint hash type that the public key fingerprint was originally hashed with. This defaults to `sha256` if not specified.

salt.states.ssh_auth.present(name, user, enc='ssh-rsa', comment='', source='', options=None, config='.ssh/authorized_keys', fingerprint_hash_type=None, **kwargs)

  Verifies that the specified SSH key is present for the specified user

  name

    The SSH key to manage

  user

    The user who owns the SSH authorized keys file to modify

  enc

    Defines what type of key is being used, can be ed25519, ecdsa, ssh-rsa, ssh-dss or any other type as of openssh server version 8.7.

  comment

    The comment to be placed with the SSH public key

  source

    The source file for the key(s). Can contain any number of public keys, in standard "authorized_keys" format. If this is set, comment and enc will be ignored.

  Note

  The source file must contain keys in the format `<enc> <key> <comment>`. If you have generated a keypair using PuTTYgen, then you will need to do the following to retrieve an OpenSSH-compatible public key.

  1. In PuTTYgen, click `Load`, and select the private key file (not the public key), and click `Open`.

  2. Copy the public key from the box labeled `Public key for pasting into OpenSSH authorized_keys file`.

  3. Paste it into a new file.

  options

    The options passed to the key, pass a list object. If set, this will overwrite the `options` to all keys in source file

  config

    The location of the authorized keys file relative to the user's home directory, defaults to ".ssh/authorized_keys". Token expansion %u and %h for username and home path supported.

  fingerprint_hash_type

    The public key fingerprint hash type that the public key fingerprint was originally hashed with. This defaults to `sha256` if not specified.
