auth.asyncio#
Module: zmq.auth.asyncio
#
ZAP Authenticator integrated with the asyncio IO loop.
Added in version 15.2.
Classes#
AsyncioAuthenticator
#
- class zmq.auth.asyncio.AsyncioAuthenticator(context: Context | None = None, loop: Any = None, encoding: str = 'utf-8', log: Any = None)#
ZAP authentication for use in the asyncio IO loop
- allow(*addresses: str) None #
Allow IP address(es).
Connections from addresses not explicitly allowed will be rejected.
For NULL, all clients from this address will be accepted.
For real auth setups, they will be allowed to continue with authentication.
allow is mutually exclusive with deny.
- configure_curve(domain: str = '*', location: str | PathLike = '.') None #
Configure CURVE authentication for a given domain.
CURVE authentication uses a directory that holds all public client certificates, i.e. their public keys.
To cover all domains, use “*”.
You can add and remove certificates in that directory at any time. configure_curve must be called every time certificates are added or removed, in order to update the Authenticator’s state
To allow all client keys without checking, specify CURVE_ALLOW_ANY for the location.
- configure_curve_callback(domain: str = '*', credentials_provider: Any = None) None #
Configure CURVE authentication for a given domain.
CURVE authentication using a callback function validating the client public key according to a custom mechanism, e.g. checking the key against records in a db. credentials_provider is an object of a class which implements a callback method accepting two parameters (domain and key), e.g.:
class CredentialsProvider(object): def __init__(self): ...e.g. db connection def callback(self, domain, key): valid = ...lookup key and/or domain in db if valid: logging.info('Authorizing: {0}, {1}'.format(domain, key)) return True else: logging.warning('NOT Authorizing: {0}, {1}'.format(domain, key)) return False
To cover all domains, use “*”.
- configure_gssapi(domain: str = '*', location: str | None = None) None #
Configure GSSAPI authentication
Currently this is a no-op because there is nothing to configure with GSSAPI.
- configure_plain(domain: str = '*', passwords: Dict[str, str] | None = None) None #
Configure PLAIN authentication for a given domain.
PLAIN authentication uses a plain-text password file. To cover all domains, use “*”. You can modify the password file at any time; it is reloaded automatically.
- context: zmq.Context#
- curve_user_id(client_public_key: bytes) str #
Return the User-Id corresponding to a CURVE client’s public key
Default implementation uses the z85-encoding of the public key.
Override to define a custom mapping of public key : user-id
This is only called on successful authentication.
- Parameters:
client_public_key (bytes) – The client public key used for the given message
- Returns:
user_id – The user ID as text
- Return type:
unicode
- deny(*addresses: str) None #
Deny IP address(es).
Addresses not explicitly denied will be allowed to continue with authentication.
deny is mutually exclusive with allow.
- log: Any#
- zap_socket: zmq.Socket#
