Helper method used to validate OpenID Connect token The Token is represented as a JSON Web Token (JWT) consists of a base64-encoded header, body, and signature, separated by '.' e.g., "Base64url.Base64url.Base64url". The First part of the token contains the header, the second part contains payload and the third part contains signature. These token parts should be Base64 URLSafe i.e., Token cannot contain characters other than a-z, A-Z, 0-9 and special characters '-', '_'. Args: token (str): Base64url-encoded OpenID connect token fetched from the file path passed via `openid_token_file` connection argument. Returns: bool: Signal indicating whether the token is valid or not. �.� Fz^[a-zA-Z0-9-_]*$c 3 s$ | ] }t |�o� �|�d uV qd S )N)�len�search)�.0Z token_part�Zurlsafe_patternr r � <genexpr>W s �zFMySQLOpenIDConnectAuthPlugin._validate_openid_token.<locals>.<genexpr>)�splitr �re�compile�all)r Zheader_payload_sigr r r �_validate_openid_token> s ��z3MySQLOpenIDConnectAuthPlugin._validate_openid_token)� auth_data�kwargsr c K s� z�| j r | js t�| j� d���|�dd�}t|�}|�� jt krLt�d��|j dd�}|� � }| � |�stt�d��| j t�t|��|�� g}d�|�W S ttttfy� } zt�d �|�W Y d}~n d}~0 0 dS ) a� Prepares authentication string for the server.
