# HANA database secrets engine

HANA is one of the supported plugins for the database secrets engine. This
plugin generates database credentials dynamically based on configured roles for
the HANA database.

See the [database secrets engine](/vault/docs/secrets/databases) docs for
more information about setting up the database secrets engine.

## Capabilities

| Plugin Name              | Root Credential Rotation | Dynamic Roles | Static Roles |
| ------------------------ | ------------------------ | ------------- | ------------ |
| `hanadb-database-plugin` | Yes (1.6+)               | Yes           | Yes (1.6+)   |

## Setup

1.  Enable the database secrets engine if it is not already enabled:

    ```text
    $ vault secrets enable database
    Success! Enabled the database secrets engine at: database/
    ```

    By default, the secrets engine will enable at the name of the engine. To
    enable the secrets engine at a different path, use the `-path` argument.

1.  Configure Vault with the proper plugin and connection information:

    ```text
    $ vault write database/config/my-hana-database \
        plugin_name=hana-database-plugin \
        connection_url="hdb://{{username}}:{{password}}@localhost:1433" \
        allowed_roles="my-role" \
        username="vaultuser" \
        password="vaultpass"
    ```

1.  Configure a role that maps a name in Vault to an SQL statement to execute to
    create the database credential:

    ```text
    $ vault write database/roles/my-role \
        db_name=my-hana-database \
        creation_statements="CREATE USER {{name}} PASSWORD {{password}} VALID UNTIL '{{expiration}}';\
            CALL GRANT_ACTIVATED_ROLE ( 'sap.hana.admin.roles::Monitoring', '{{name}}' );" \
        default_ttl="12h" \
        max_ttl="24h"
    Success! Data written to: database/roles/my-role
    ```

## Usage

After the secrets engine is configured and a user/machine has a Vault token with
the proper permission, it can generate credentials.

1.  Generate a new credential by reading from the `/creds` endpoint with the name
    of the role:

    ```text
    $ vault read database/creds/my-role
    Key                Value
    ---                -----
    lease_id           database/creds/my-role/2f6a614c-4aa2-7b19-24b9-ad944a8d4de6
    lease_duration     1h
    lease_renewable    true
    password           sU4zWnITaABEP-Zwy4sF
    username           v_vaultuser_my_role_jQbCLE6P2VtgsqPBXK0m_1602541873
    ```
