This class represents a set of GSSAPI credentials which may
be used with and/or returned by other GSSAPI methods.
It inherits from the low-level GSSAPI :class:`~gssapi.raw.creds.Creds`
class, and thus may used with both low-level and high-level API methods.
If your implementation of GSSAPI supports the credentials import-export
extension, you may pickle and unpickle this object.
The constructor either acquires or imports a set of GSSAPI
credentials.
If the `base` argument is used, an existing
:class:`~gssapi.raw.creds.Cred` object from the low-level API is
converted into a high-level object.
If the `token` argument is used, the credentials
are imported using the token, if the credentials import-export
extension is supported (:requires-ext:`cred_imp_exp`).
Otherwise, the credentials are acquired as per the
:meth:`acquire` method.
Raises:
BadMechanismError
BadNameTypeError
BadNameError
ExpiredCredentialsError
MissingCredentialsError

�S )a Acquire GSSAPI credentials
This method acquires credentials. If the `store` argument is
used, the credentials will be acquired from the given
credential store (if supported). Otherwise, the credentials are
acquired from the default store.
The credential store information is a dictionary containing
mechanisms-specific keys and values pointing to a credential store
or stores.
Using a non-default store requires support for the credentials store
extension.
Args:
name (Name): the name associated with the credentials,
or None for the default name
lifetime (int): the desired lifetime of the credentials, or None
for indefinite
mechs (list): the desired :class:`MechType` OIDs to be used
with the credentials, or None for the default set
usage (str): the usage for the credentials -- either 'both',
'initiate', or 'accept'
store (dict): the credential store information pointing to the
credential store from which to acquire the credentials,
or None for the default store (:requires-ext:`cred_store`)
Returns:
AcquireCredResult: the acquired credentials and information about
them
Raises:
BadMechanismError
BadNameTypeError
BadNameError
ExpiredCredentialsError
MissingCredentialsError

This method stores the current credentials into the specified
credentials store. If the default store is used, support for
:rfc:`5588` is required. Otherwise, support for the credentials
store extension is required.
:requires-ext:`rfc5588` or :requires-ext:`cred_store`
Args:
store (dict): the store into which to store the credentials,
or None for the default store.
usage (str): the usage to store the credentials with -- either
'both', 'initiate', or 'accept'
mech (OID): the :class:`MechType` to associate with the
stored credentials
overwrite (bool): whether or not to overwrite existing credentials
stored with the same name, etc
set_default (bool): whether or not to set these credentials as
the default credentials for the given store.
Returns:
StoreCredResult: the results of the credential storing operation
Raises:

�S )a Acquire more credentials to add to the current set
This method works like :meth:`acquire`, except that it adds the
acquired credentials for a single mechanism to a copy of the current
set, instead of creating a new set for multiple mechanisms.
Unlike :meth:`acquire`, you cannot pass None desired name or
mechanism.
If the `impersonator` argument is used, the credentials will
impersonate the given name using the impersonator credentials
(:requires-ext:`s4u`).
If the `store` argument is used, the credentials will be acquired
from the given credential store (:requires-ext:`cred_store`).
Otherwise, the credentials are acquired from the default store.
The credential store information is a dictionary containing
mechanisms-specific keys and values pointing to a credential store
or stores.
Note that the `store` argument is not compatible with the
`impersonator` argument.
Args:
name (Name): the name associated with the
credentials
mech (OID): the desired :class:`MechType` to be used with the
credentials
usage (str): the usage for the credentials -- either 'both',
'initiate', or 'accept'
init_lifetime (int): the desired initiate lifetime of the
credentials, or None for indefinite
accept_lifetime (int): the desired accept lifetime of the
credentials, or None for indefinite
impersonator (Credentials): the credentials to use to impersonate
the given name, or None to not acquire normally
(:requires-ext:`s4u`)
store (dict): the credential store information pointing to the
credential store from which to acquire the credentials,
or None for the default store (:requires-ext:`cred_store`)
Returns:
Credentials: the credentials set containing the current credentials
and the newly acquired ones.
Raises:
BadMechanismError
BadNameTypeError
BadNameError
DuplicateCredentialsElementError
ExpiredCredentialsError
MissingCredentialsError
