# Keys API

## Get SSH key with user by ID of an SSH key

Get SSH key with user by ID of an SSH key. Note only administrators can lookup SSH key with user by ID of an SSH key.

```plaintext

```

| Attribute | Type    | Required | Description          |
|:----------|:--------|:---------|:---------------------|
| `id`      | integer | yes      | The ID of an SSH key |

Example request:

```shell
curl --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/keys/1"
```

## Get user by fingerprint of SSH key

You can search for a user that owns a specific SSH key. Note only administrators can lookup SSH key with the fingerprint of an SSH key.

```plaintext
GET /keys
```

| Attribute     | Type   | Required | Description                   |
|:--------------|:-------|:---------|:------------------------------|
| `fingerprint` | string | yes      | The fingerprint of an SSH key |

Example request:

```shell
curl --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/keys?fingerprint=ba:81:59:68:d7:6c:cd:02:02:bf:6a:9b:55:4e:af:d1"
```

If using sha256 fingerprint API calls, make sure that the fingerprint is URL-encoded.

For example, `/` is represented by `%2F` and `:` is represented by`%3A`:

```shell
curl --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/keys?fingerprint=SHA256%3AnUhzNyftwADy8AH3wFY31tAKs7HufskYTte2aXo%2FlCg"
```

## Get user by deploy key fingerprint

> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/119209) in GitLab 12.7.

Deploy keys are bound to the creating user, so if you query with a deploy key
fingerprint you get additional information about the projects using that key.

Example request:

```shell
curl --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/keys?fingerprint=SHA256%3AnUhzNyftwADy8AH3wFY31tAKs7HufskYTte2aXo%2FlCg"
```
