2.43.0 (2025-11-05)

Features

• Add public wrapper for _mtls_helper.check_use_client_cert which enables mTLS if GOOGLE_API_USE_CLIENT_CERTIFICATE is not set, when the MWID/X.509 cert sources detected (#1859) Add public wrapper for check_use_client_cert which enables mTLS if GOOGLE_API_USE_CLIENT_CERTIFICATE is not set, when the MWID/X.509 cert sources detected. Also, fix check_use_client_cert to return boolean value. Change #1848 added the check_use_client_cert method that helps know if client cert should be used for mTLS connection. However, that was in a private class, thus, created a public wrapper of the same function so that it can be used by python Client Libraries. Also, updated check_use_client_cert to return a boolean value instead of existing string value for better readability and future scope. --------- (1535eccbff0ad8f3fd6a9775316ac8b77dca66ba)
• Enable mTLS if GOOGLE_API_USE_CLIENT_CERTIFICATE is not set, if the MWID/X.509 cert sources detected (#1848) The Python SDK will use a hybrid approach for mTLS enablement:

• If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is set (either true or false), the SDK will respect that setting. This is necessary for test scenarios and users who need to explicitly control mTLS behavior.
• If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is not set, the SDK will automatically enable mTLS only if it detects Managed Workload Identity (MWID) or X.509 Workforce Identity Federation (WIF) certificate sources. In other cases where the variable is not set, mTLS will remain disabled. ** This change also adds the helper method check_use_client_cert and it's unit test, which will be used for checking the criteria for setting the mTLS to true ** This change is only for Auth-Library, other changes will be created for Client-Library use-cases. --------- (395e405b64b56ddb82ee639958c2e8056ad2e82b)
