## 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"
```
