# ssh-agent plugin

This plugin starts automatically `ssh-agent` to set up and load whichever
credentials you want for ssh connections.

To enable it, add `ssh-agent` to your plugins:

```zsh
plugins=(... ssh-agent)
```

## Settings

**IMPORTANT: put these settings _before_ the line that sources oh-my-zsh**

To enable **agent forwarding support** add the following to your zshrc file:

```zsh
zstyle :omz:plugins:ssh-agent agent-forwarding on
```

----

To **load multiple identities** use the `identities` style, For example:

```zsh
zstyle :omz:plugins:ssh-agent identities id_rsa id_rsa2 id_github
```

**NOTE:** the identities may be an absolute path if they are somewhere other than
`~/.ssh`. For example:

```zsh
zstyle :omz:plugins:ssh-agent identities ~/.config/ssh/id_rsa ~/.config/ssh/id_rsa2 ~/.config/ssh/id_github
# which can be simplified to
zstyle :omz:plugins:ssh-agent identities ~/.config/ssh/{id_rsa,id_rsa2,id_github}
```

----

To **set the maximum lifetime of the identities**, use the `lifetime` style.
The lifetime may be specified in seconds or as described in sshd_config(5)
(see _TIME FORMATS_). If left unspecified, the default lifetime is forever.

```zsh
zstyle :omz:plugins:ssh-agent lifetime 4h
```

----

To **pass arguments to the `ssh-add` command** that adds the identities on startup,
use the `ssh-add-args` setting. You can pass multiple arguments separated by spaces:

```zsh
zstyle :omz:plugins:ssh-agent ssh-add-args -K -c -a /run/user/1000/ssh-auth
```

These will then be passed the the `ssh-add` call as if written directly. The example
above will turn into:

```zsh
ssh-add -K -c -a /run/user/1000/ssh-auth <identities>
```

For valid `ssh-add` arguments run `ssh-add --help` or `man ssh-add`.

----

To set an **external helper** to ask for the passwords and possibly store
them in the system keychain use the `helper` style. For example:

```zsh
zstyle :omz:plugins:ssh-agent helper ksshaskpass
```
