# trust key-generate
```markdown
Usage: docker trust key-generate NAME
Generate and load a signing key-pair
```
## Description
`docker trust key-generate` generates a key-pair to be used with signing,
and loads the private key into the local docker trust keystore.
`docker trust key-generate` is currently experimental.
## Examples
### Generate a key-pair
```bash
$ docker trust key-generate alice
Generating key for alice...
Enter passphrase for new alice key with ID 17acf3c:
Repeat passphrase for new alice key with ID 17acf3c:
Successfully generated and loaded private key. Corresponding public key available: alice.pub
$ ls
alice.pub
```
The private signing key is encrypted by the passphrase and loaded into the docker trust keystore.
All passphrase requests to sign with the key will be referred to by the provided `NAME`.
The public key component `alice.pub` will be available in the current working directory, and can
be used directly by `docker trust signer-add`.

# trust key-load
```markdown
Usage: docker trust key-load [OPTIONS] KEY
Load a signing key
```
## Description
`docker trust key-load` adds private keys to the local docker trust keystore. To add a signer to a repository use `docker trust signer-add`.
`docker trust key-load` is currently experimental.
## Examples
### Load a single private key
For a private key `alice.pem` with permissions `-rw-------`
```bash
$ docker trust key-load alice.pem
Loading key from "alice.pem"...
Enter passphrase for new signer key with ID f8097df:
Repeat passphrase for new signer key with ID f8097df:
Successfully imported key from alice.pem
```
to specify a name use the `--name` flag
```bash
$ docker trust key-load --name alice-key alice.pem
Loading key from "alice.pem"...
Enter passphrase for new alice-key key with ID f8097df:
Repeat passphrase for new alice-key key with ID f8097df:
Successfully imported key from alice.pem

# trust signer-add
```markdown
Usage: docker trust signer-add [OPTIONS] NAME IMAGE [IMAGE...]
Add a signer to one or more repositories
```
## Description
`docker trust signer-add` adds signers to signed repositories.
`docker trust signer-add` is currently experimental.
## Examples
### Add a signer to a repo
To add a new signer, `alice`, to this repository:
```bash
$ docker trust inspect example/trust-demo
No signatures for example/trust-demo
List of signers and their keys:
SIGNER KEYS
bob 5600f5ab76a2
Administrative keys for example/trust-demo:
Repository Key: 642692c14c9fc399da523a5f4e24fe306a0a6ee1cc79a10e4555b3c6ab02f71e
Root Key: 3cb2228f6561e58f46dbc4cda4fcaff9d5ef22e865a94636f82450d1d2234949
```
Add `alice` with `docker trust signer-add`:
```bash
$ docker trust signer-add alice example/trust-demo --key alice.crt
Adding signer "alice" to example/trust-demo...
Enter passphrase for repository key with ID 642692c:
Successfully added signer: alice to example/trust-demo
```
`docker trust inspect` now lists `alice` as a valid signer:
```bash
$ docker trust inspect example/trust-demo
No signatures for example/trust-demo
List of signers and their keys:
SIGNER KEYS
alice 05e87edcaecb

```
## Initialize a new repo and add a signer
When adding a signer on a repo for the first time, `docker trust signer-add` sets up a new repo if it doesn't exist.
```bash
$ docker trust inspect example/trust-demo
No signatures or cannot access example/trust-demo
```
```bash
$ docker trust signer-add alice example/trust-demo --key alice.crt
Initializing signed repository for example/trust-demo...
Enter passphrase for root key with ID 748121c:
Enter passphrase for new repository key with ID 95b9e55:
Repeat passphrase for new repository key with ID 95b9e55:
Successfully initialized "example/trust-demo"
Adding signer "alice" to example/trust-demo...
Successfully added signer: alice to example/trust-demo
```
```bash
$ docker trust inspect example/trust-demo

`docker trust signer-add` adds signers to repositories on a best effort basis, so it will continue to add the signer to subsequent repositories if one attempt fails:
```bash
