Syntax conventions

## Description

The user or the administrator uses this command to:

- upload a user’s public SSH key onto the server
- force an update of the user’s key that overwrites the old key
- delete a user’s key

### Scope

When you upload a user’s public SSH key onto the server, if you do not specify an explicit scope, the key gets `default` as its implicit scope name.

If a user has more than one computer, and thus more than one SSH key, we recommend that you assign an explicit `scope` name for each key. A typical scope name might be a physical location, such as `home` or `office`, or a computer name, such as `server1`, `macintosh_laptop`, or `Windows_desktop`.

When you delete a key associated with the specified user, if you do not specify an explicit scope, this command deletes the key with the implicit `default` scope.

You cannot update the scope, but you can delete the key and generate a new key with whatever scope you want.

To get a listing of all the keys and scopes for a specific user, see the `p4 pubkeys` topic, Examples.

### Prerequisite for a user to upload a key

The prerequisite to being able to upload a SSH public key on the P4 Server is to have, at a minimum, the `list` access to a filename in the protections table. Let us assume that the P4 Server administrator wants the protections table to provide only this minimum access.

As super user, the administrator issues the `p4 protect` command, which opens the `Protections` form.

The administrator fills out the `Protections` form to specify that members of a group named `repoUsers` have `list` access to a specific file:

    list group repoUsers * //depot/no-file.txt

Note that `no-file.txt` does not need to be an actual file.

The administrator issues the `p4 group` command with the `repoUsers` group name:

    p4 group repoUsers

In the Group Specification form, the administrator adds the names of the users who belong to the `repoUsers` group.

## Options

`-d` | Deletes the key for the specified user. If you do not specify a scope, deletes the specified user’s key that has the `default` scope. If you specify a scope, deletes the key associated with that scope.
`-f` | The `-f` option allows a user or an administrator to force an overwrite of the user’s existing key.
`-i entry-from-standard-input` | Uploads the public SSH key from the location specified in a standard input redirect.
`-s` scope | Assigns a scope to this public key, which is useful if a given user has more than one key. If you do not use this option to specify a scope, the scope is set to `default` automatically.
-u username | Administrators can associate the key with a specific user. There is no check to validate whether the specified user actually exists.
`g-opts` | See Global options.

## Examples

#### Upload with scope

The user indicates the location of the key with a standard input redirect. A best practice is to provide an explicit scope that helps the user identify which computer the key belongs to. The explicit scope also ensures the user does not inadvertently overwrite the implicit scope, which has `default` as its implicit name.

    p4 pubkey -i < path/to/your/.ssh/id_rsa.pub -s mac-laptop

The admin can upload the key for the user by including the `-u` username option.

    p4 pubkey -i < path/to/your/.ssh/id_rsa.pub -u bruno -s mac-laptop

#### Force an update to an existing key

If a message appears that is similar to the following:

`Public Key for 'bruno/mac-laptop' already exists, use '-f' to replace.`

To force the overwrite of an existing key, include the `-f` force option.

    p4 pubkey -f -u bruno -s mac-laptop -i < path/to/your/.ssh/id_rsa.pub

#### Delete a key

To delete the SSH public key for the specified user and the `default` scope, which is implicit.

    p4 pubkey -d -u bruno

To delete the SSH public key for the specified user and scope.

    p4 pubkey -d -u bruno -s windows-laptop
