# trust view

```markdown
Usage:  docker trust view IMAGE[:TAG]

Display detailed information about keys and signatures

```

## Description

`docker trust view` provides detailed information on signed repositories.
This includes all image tags that are signed, who signed them, and who can sign
new tags.

By default, `docker trust view` renders results in a table.

`docker trust view` is currently experimental.


## Examples

### Get details about signatures for a single image tag


```bash
$ docker trust view alpine:latest

SIGNED TAG          DIGEST                                                             SIGNERS

Administrative keys for alpine:latest:
Repository Key:	5a46c9aaa82ff150bb7305a2d17d0c521c2d784246807b2dc611f436a69041fd

```

The `SIGNED TAG` is the signed image tag with a unique content-addressable `DIGEST`. `SIGNERS` lists all entities who have signed.

The administrative keys listed specify the root key of trust, as well as the administrative repository key. These keys are responsible for modifying signers, and rotating keys for the signed repository.

If signers are set up for the repository via other `docker trust` commands, `docker trust view` displays them appropriately as a `SIGNER` and specify their `KEYS`:

```bash
$ docker trust view my-image:purple
SIGNED TAG          DIGEST                                                              SIGNERS

```

If the image tag is unsigned or unavailable, `docker trust view` does not display any signed tags.

```bash
$ docker trust view unsigned-img
No signatures or cannot access unsigned-img
```

However, if other tags are signed in the same image repository, `docker trust view` reports relevant key information.

```bash
$ docker trust view alpine:unsigned

No signatures for alpine:unsigned


Administrative keys for alpine:unsigned:
