# Cassandra

> Learn how to dynamically generate Cassandra database user credentials

The Infisical Cassandra dynamic secret allows you to generate Cassandra database credentials on demand based on configured role.

## Prerequisite

Infisical requires a Cassandra user in your instance with the necessary permissions. This user will facilitate the creation of new accounts as needed.
Ensure the user possesses privileges for creating, dropping, and granting permissions to roles for it to be able to create dynamic secrets.

<Tip>
  In your Cassandra configuration file `cassandra.yaml`, make sure you have the following settings:

  ```yaml  theme={"dark"}
  authenticator: PasswordAuthenticator
  authorizer: CassandraAuthorizer
  ```
</Tip>

The above configuration allows user creation and granting permissions.

## Set up Dynamic Secrets with Cassandra

<Steps>
  <Step title="Open Secret Overview Dashboard">
    Open the Secret Overview dashboard and select the environment in which you would like to add a dynamic secret.
  </Step>

      Password that will be used to create dynamic secrets
    </ParamField>

    <ParamField path="Local Data Center" type="string" required>

    </ParamField>

    <ParamField path="Keyspace" type="string">
      Keyspace name where you want to create dynamic secrets. This ensures that the user is limited to that keyspace.
    </ParamField>

    <ParamField path="CA(SSL)" type="string">
      A CA may be required if your cassandra requires it for incoming connections.
    </ParamField>

  </Step>

  <Step title="(Optional) Modify CQL Statements">
        <img src="https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/platform/dynamic-secrets/modify-cql-statements.png" alt="Modify CQL Statements Modal" />

    <ParamField path="Username Template" type="string" default="{{randomUsername}}">
      Specifies a template for generating usernames. This field allows customization of how usernames are automatically created.

      Allowed template variables are:

      * `{{randomUsername}}`: Random username string.
      * `{{unixTimestamp}}`: Current Unix timestamp at the time of lease creation.
      * `{{identity.name}}`: Name of the identity that is generating the lease.
      * `{{dynamicSecret.name}}`: Name of the associated dynamic secret.
      * `{{dynamicSecret.type}}`: Type of the associated dynamic secret.
      * `{{random N}}`: Random string of N characters.

      Allowed template functions are:

      * `truncate`: Truncates a string to a specified length.
      * `replace`: Replaces a substring with another value.
      * `uppercase`: Converts a string to uppercase.
      * `lowercase`: Converts a string to lowercase.

      Examples:

      ```yaml  theme={"dark"}
      {{ randomUsername }}                                            // 3POnzeFyK9gW2nioK0q2gMjr6CZqsRiX
      {{ unixTimestamp }}                                             // 17490641580
      {{ identity.name }}                                             // <identity-name>
      {{ random 5 }}                                                  // x9K2m
      {{ truncate identity.name 4 }}                                  // test
      {{ replace identity.name '<identity-name>' 'new-value' }}       // new-value
      ```
    </ParamField>

    <ParamField path="Customize CQL Statement" type="string">
      If you want to provide specific privileges for the generated dynamic credentials, you can modify the CQL statement to your needs. This is useful if you want to only give access to a specific key-space(s).
    </ParamField>
  </Step>

  <Step title="Click 'Submit'">
    After submitting the form, you will see a dynamic secret created in the dashboard.

    <Note>
      If this step fails, you may have to add the CA certificate.
    </Note>

  </Step>

  <Step title="Generate dynamic secrets">
    Once you've successfully configured the dynamic secret, you're ready to generate on-demand credentials.
    To do this, simply click on the 'Generate' button which appears when hovering over the dynamic secret item.
    Alternatively, you can initiate the creation of a new lease by selecting 'New Lease' from the dynamic secret lease list section.

    <img src="https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/platform/dynamic-secrets/dynamic-secret-lease-empty.png" alt="Dynamic Secret" />

    When generating these secrets, it's important to specify a Time-to-Live (TTL) duration. This will dictate how long the credentials are valid for.

    <Tip>
      Ensure that the TTL for the lease falls within the maximum TTL defined when configuring the dynamic secret in step 4.
    </Tip>

    Once you click the `Submit` button, a new secret lease will be generated and the credentials for it will be shown to you.

  </Step>
</Steps>

## Audit or Revoke Leases

Once you have created one or more leases, you will be able to access them by clicking on the respective dynamic secret item on the dashboard.
This will allow you to see the lease details and delete the lease ahead of its expiration time.

## Renew Leases

To extend the life of the generated dynamic secret lease past its initial time to live, simply click on the **Renew** button as illustrated below.

<Warning>
  Lease renewals cannot exceed the maximum TTL set when configuring the dynamic secret
