RenewableCerta Renewable certificate.
Represents a lineage of certificates that is under the management of
Certbot, indicated by the existence of an associated renewal
configuration file.
Note that the notion of "current version" for a lineage is
maintained on disk in the structure of symbolic links, and is not
explicitly stored in any instance variable in this object. The
RenewableCert object is able to determine information about the
current (or other) version by accessing data on disk, but does not
inherently know any of this information except by examining the
symbolic links as needed. The instance variables mentioned below
point to symlinks that reflect the notion of "current version" of
each managed object, and it is these paths that should be used when
configuring servers to use the certificate managed in a lineage.
These paths are normally within the "live" directory, and their
symlink targets -- the actual cert files -- are normally found
within the "archive" directory.
:ivar str cert: The path to the symlink representing the current
version of the certificate managed by this lineage.
:ivar str privkey: The path to the symlink representing the current
version of the private key managed by this lineage.
:ivar str chain: The path to the symlink representing the current version
of the chain managed by this lineage.
:ivar str fullchain: The path to the symlink representing the
current version of the fullchain (combined chain and cert)
managed by this lineage.
:ivar configobj.ConfigObj configuration: The renewal configuration
options associated with this lineage, obtained from parsing the
renewal configuration file and/or systemwide defaults.

This is a policy question and does not only depend on whether
the cert is expired. (This considers whether autorenewal is
enabled, whether the cert is revoked, and whether the time
interval for autorenewal has been reached.)
Note that this examines the numerically most recent cert version,
not the currently deployed version.
:returns: whether an attempt should now be made to autorenew the
most current cert version in this lineage

|�}| |j"|�S )a� Create a new certificate lineage.
Attempts to create a certificate lineage -- enrolled for
potential future renewal -- with the (suggested) lineage name
lineagename, and the associated cert, privkey, and chain (the
associated fullchain will be created automatically). Optional
configurator and renewalparams record the configuration that was
originally used to obtain this cert, so that it can be reused
later during automated renewal.
Returns a new RenewableCert object referring to the created
lineage. (The actual lineage name, as well as all the relevant
file paths, will be available within this object.)
:param str lineagename: the suggested name for this lineage
(normally the current cert's first subject DNS name)
:param str cert: the initial certificate version in PEM format
:param str privkey: the private key in PEM format
:param str chain: the certificate chain in PEM format
:param .NamespaceConfig cli_config: parsed command line
arguments
:returns: the newly-created RenewalCert object

Returns the new version number that was created.

version

is regarded as a successor (used to choose a privkey, if the
key has not changed, but otherwise this information is not
permanently recorded anywhere)
:param bytes new_cert: the new certificate, in PEM format
:param bytes new_privkey: the new private key, in PEM format,
