+# notation certificate
+
+## Description
+
+Use ```notation certificate``` command to add/list/delete certificates in notation's trust store. Updating an existing certificate is not allowed since the thumbprint will be inconsistent, which results in a new certificate.
+
+The trust store is in the format of a directory in the filesystem as`x509/<type>/<name>/*.crt|*.cer|*.pem`. Currently two types of trust store are supported:
+
+* `Certificate Authority`: The directory name is `ca`.
+* `Signing Authority`: The directory name is `signingAuthority`
+
+There could be more trust store types introduced in the future.
+
+Here is an example of trust store directory structure:
+
+```text
+$XDG_CONFIG_HOME/notation/truststore
+    /x509
+        /ca
+            /acme-rockets
+                cert1.pem
+                cert2.pem
+                  /sub-dir       # sub directory is ignored
+                    cert-3.pem   # certs under sub directory is ignored
+
+        /signingAuthority
+            /wabbit-networks
+                cert3.crt
+```
+
+In this example, there are two certificates stored in trust store named `acme-rockets` of type `ca`. There is one certificate stored in trust store named `wabbit-networks` of type `signingAuthority`.

+
+```bash
+notation certificate add --type <type> --store <name> <cert_path>...
+```
+
+For each certificate in a certificate file, it MUST be either CA type or self-signed.
+
+Upon successful adding, the certificate files are added into directory`{NOTATION_CONFIG}/truststore/x509/<type>/<name>/`, and a list of certificate filepaths are printed out. If the adding fails, an error message is printed out by listing which certificate files are successfully added, and which certificate files are not along with detailed reasons.
+
+### List all certificate files stored in the trust store
+
+```bash
+notation certificate list
+```
+
+Upon successful listing, all the certificate files in the trust store are printed out in a format of absolute filepath. If the listing fails, an error message is printed out with specific reasons. Nothing is printed out if the trust store is empty.
+
+### List all certificate files of a certain named store
+
+```bash
+notation cert list --store <name>
+```
+
+Upon successful listing, all the certificate files in the trust store named `<name>` are printed out in a format of absolute filepath. If the listing fails, an error message is printed out with specific reasons. Nothing is printed out if the trust store is empty.
+
+### List all certificate files of a certain type of store
+
+```bash
+notation cert list --type <type>
+```
+
+Upon successful listing, all the certificate files in the trust store of type `<type>` are printed out in a format of absolute filepath. If the listing fails, an error message is printed out with specific reasons. Nothing is printed out if the trust store is empty.
+
+### List all certificate files of a certain named store of a certain type
+
+```bash
+notation cert list --type <type> --store <name>
+```
+
+Upon successful listing, all the certificate files in the trust store named `<name>` of type `<type>` are printed out in a format of absolute filepath. If the listing fails, an error message is printed out with specific reasons. Nothing is printed out if the trust store is empty.
+
+### Show details of a certain certificate file
+
+```bash
+notation certificate show --type <type> --store <name> <cert_fileName>
+```
+
+Upon successful show, the certificate details are printed out starting from leaf certificate if it's a certificate chain. Here is a list of certificate properties:
+
+* Issuer
+* Subject
+* Valid from
+* Valid to
+* IsCA
+* Thumbprints
+
+If the showing fails, an error message is printed out with specific reasons.
+
+### Delete all certificates of a certain named store of a certain type
+
+```bash
+notation certificate delete --type <type> --store <name> --all
+```
+
+A prompt is showed asking user to confirm the deletion. Upon successful deletion, all certificates in trust store named `<name>` of type `<type>` are deleted. If deletion fails, a list of successful deleted certificate files is printed out as well as a list of deletion-failure certificates with specific reasons.
+
+### Delete a specific certificate of a certain named store of a certain type
+
+```bash
+notation certificate delete --type <type> --store <name> <cert_fileName>
+```
+
+A prompt is showed asking user to confirm the deletion. Upon successful deletion, the specific certificate is deleted in trust store named `<name>` of type `<type>`. If deletion fails, an error message with specific reasons is printed out.
+
+### Generate a local RSA key and a corresponding self-generated certificate for testing purpose and add the certificate into trust store
+
+```bash
+notation certificate generate-test --trust "wabbit-networks.io"
+```
+
+Upon successful execution, a local key file and certificate file named `wabbit-networks.io` are generated and stored in `$XDG_CONFIG_HOME/notation/localkeys/`. `wabbit-networks.io` is also used as certificate subject.CommonName. With `--trust` flag set, the certificate is added into a trust store named `wabbit-networks.io` of type `ca`.

+
+```shell
+notation key add --default --plugin <plugin_name> --id <remote_key_id> <key_name>
+```
+
+Upon successful adding, a key name is printed out for added signing key with additional info "marked as default".

+### Update the default signing key
+
+```shell
+notation key update --default <key_name>
+```
+
+Upon successful update, the supplied key name is printed out with additional info "marked as default".
+
+### List signing keys
+
+```text
+notation key list
+```
+
+Upon successful execution, a list of keys is printed out with information of name, key path, certificate path, key id and plugin name. The default signing key name is preceded by an asterisk. The key id and plugin name are used together to provide the information of the key identifier for the remote key and the plugin associated with it.
+
+### Delete two keys from signing key list
+
+```shell
+notation key delete <key_name_1> <key_name_2>
+```
+
+Upon successful execution, the names of deleted signing keys are printed out. Please be noted if default signing key is deleted, Notation will not automatically assign a new default signing key. User needs to update the default signing key explicitly.
