Creates and uploads a client-side encryption S/MIME public key certificate chain and private key metadata for the authenticated user. For administrators managing identities and keypairs for users in their organization, requests require authorization with a [service account](https://developers.google.com/identity/protocols/OAuth2ServiceAccount) that has [domain-wide delegation authority](https://developers.google.com/identity/protocols/OAuth2ServiceAccount#delegatingauthority) to impersonate users with the `https://www.googleapis.com/auth/gmail.settings.basic` scope. For users managing their own identities and keypairs, requests require [hardware key encryption](https://support.google.com/a/answer/14153163) turned on and configured.

Turns off a client-side encryption key pair. The authenticated user can no longer use the key pair to decrypt incoming CSE message texts or sign outgoing CSE mail. To regain access, use the EnableCseKeyPair to turn on the key pair. After 30 days, you can permanently delete the key pair by using the ObliterateCseKeyPair method.

Deletes a client-side encryption key pair permanently and immediately. You can only permanently delete key pairs that have been turned off for more than 30 days. To turn off a key pair, use the DisableCseKeyPair method. Gmail can't restore or decrypt any messages that were encrypted by an obliterated key. Authenticated users and Google Workspace administrators lose access to reading the encrypted messages.

Gmail uses the key pair to complete the following tasks: - Sign outgoing client-side encrypted messages. - Save and reopen drafts of client-side encrypted messages. - Save and reopen sent messages. - Decrypt incoming or archived S/MIME messages. For administrators managing identities and keypairs for users in their organization, requests require authorization with a [service account](https://developers.google.com/identity/protocols/OAuth2ServiceAccount) that has [domain-wide delegation authority](https://developers.google.com/identity/protocols/OAuth2ServiceAccount#delegatingauthority) to impersonate users with the `https://www.googleapis.com/auth/gmail.settings.basic` scope. For users managing their own identities and keypairs, requests require [hardware key encryption](https://support.google.com/a/answer/14153163) turned on and configured.

`list_next()`

    Retrieves the next page of results.

            Args:
              previous_request: The request for the previous page. (required)
              previous_response: The response from the request for the previous page. (required)

            Returns:
              A request object that you can call 'execute()' on to request the next
              page. Returns None if there are no more items in the collection.

`obliterate(userId, keyPairId, body=None, x__xgafv=None)`

    Deletes a client-side encryption key pair permanently and immediately. You can only permanently delete key pairs that have been turned off for more than 30 days. To turn off a key pair, use the DisableCseKeyPair method. Gmail can't restore or decrypt any messages that were encrypted by an obliterated key. Authenticated users and Google Workspace administrators lose access to reading the encrypted messages. For administrators managing identities and keypairs for users in their organization, requests require authorization with a [service account](https://developers.google.com/identity/protocols/OAuth2ServiceAccount) that has [domain-wide delegation authority](https://developers.google.com/identity/protocols/OAuth2ServiceAccount#delegatingauthority) to impersonate users with the `https://www.googleapis.com/auth/gmail.settings.basic` scope. For users managing their own identities and keypairs, requests require [hardware key encryption](https://support.google.com/a/answer/14153163) turned on and configured.

    Args:
      userId: string, The requester's primary email address. To indicate the authenticated user, you can use the special value `me`. (required)
      keyPairId: string, The identifier of the key pair to obliterate. (required)
      body: object, The request body.
        The object takes the form of:

    { # Request to obliterate a CSE key pair.
    }

      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format
