All cryptographic operations in GPGME are performed within a
context, which contains the internal state of the operation as
well as configuration parameters. By using several contexts you
can run several cryptographic operations in parallel, with
different configuration.
Access to a context must be synchronized.

|S )a Decrypt data
Decrypt the given ciphertext and verify any signatures. If
VERIFY is an iterable of keys, the ciphertext must be signed
by all those keys, otherwise a MissingSignatures error is
raised. Note: if VERIFY is an empty iterable, that is treated
the same as passing verify=True (that is, verify signatures
and return data about any valid signatures found, but no
signatures are required and no MissingSignatures error will be
raised).
If the ciphertext is symmetrically encrypted using a
passphrase, that passphrase can be given as parameter, using a
callback registered at the context, or out-of-band via
pinentry.
Keyword arguments:
sink -- write result to sink instead of returning it
passphrase -- for symmetric decryption
verify -- check signatures (boolean or iterable of keys,
see above) (default True)
Returns:
plaintext -- the decrypted data (or None if sink is given)
result -- additional information about the decryption
verify_result -- additional information about the valid
signature(s) found
Raises:

MissingSignatures -- if expected signatures are missing or bad

Exports secret keys matching the pattern specified. If no

passphrase is not entered or does not match then no data will be
exported. This is the same result as when specifying a pattern
that is not matched by the available keys.
Keyword arguments:

Create a primary key for the user id USERID.
ALGORITHM may be used to specify the public key encryption
algorithm for the new key. By default, a reasonable default
is chosen. You may use "future-default" to select an
algorithm that will be the default in a future implementation
of the engine. ALGORITHM may be a string like "rsa", or
"rsa2048" to explicitly request an algorithm and a key size.
EXPIRES_IN specifies the expiration time of the key in number
of seconds since the keys creation. By default, a reasonable
expiration time is chosen. If you want to create a key that
does not expire, use the keyword argument EXPIRES.
SIGN, ENCRYPT, CERTIFY, and AUTHENTICATE can be used to
request the capabilities of the new key. If you don't request
any, a reasonable set of capabilities is selected, and in case
of OpenPGP, a subkey with a reasonable set of capabilities is
created.
If PASSPHRASE is None (the default), then the key will not be
protected with a passphrase. If PASSPHRASE is a string, it
will be used to protect the key. If PASSPHRASE is True, the
passphrase must be supplied using a passphrase callback or
out-of-band with a pinentry.
Keyword arguments:
algorithm -- public key algorithm, see above (default: reasonable)
expires_in -- expiration time in seconds (default: reasonable)
expires -- whether or not the key should expire (default: True)
sign -- request the signing capability (see above)
encrypt -- request the encryption capability (see above)
certify -- request the certification capability (see above)
authenticate -- request the authentication capability (see above)
passphrase -- protect the key with a passphrase (default: no
passphrase)
force -- force key creation even if a key with the same userid
exists (default: False)

Create a subkey for the given KEY. As subkeys are a concept
of OpenPGP, calling this is only valid for the OpenPGP
protocol.
ALGORITHM may be used to specify the public key encryption
algorithm for the new subkey. By default, a reasonable
default is chosen. You may use "future-default" to select an
algorithm that will be the default in a future implementation
of the engine. ALGORITHM may be a string like "rsa", or
"rsa2048" to explicitly request an algorithm and a key size.
EXPIRES_IN specifies the expiration time of the subkey in
number of seconds since the subkeys creation. By default, a
reasonable expiration time is chosen. If you want to create a
subkey that does not expire, use the keyword argument EXPIRES.
SIGN, ENCRYPT, and AUTHENTICATE can be used to request the
capabilities of the new subkey. If you don't request any, an
encryption subkey is generated.
If PASSPHRASE is None (the default), then the subkey will not
be protected with a passphrase. If PASSPHRASE is a string, it
will be used to protect the subkey. If PASSPHRASE is True,
the passphrase must be supplied using a passphrase callback or
out-of-band with a pinentry.
Keyword arguments:

expires_in -- expiration time in seconds (default: reasonable)
expires -- whether or not the subkey should expire (default: True)
sign -- request the signing capability (see above)

engine.
If command is a string or bytes, it will be used as-is. If it
is an iterable of strings, it will be properly escaped and
joined into an well-formed assuan command.
Keyword arguments:

A lot of data has to be exchanged between the user and the crypto
engine, like plaintext messages, ciphertext, signatures and
information about the keys. The technical details about
exchanging the data information are completely abstracted by
GPGME. The user provides and receives the data via `gpgme_data_t'
objects, regardless of the communication protocol between GPGME
and the crypto engine in use.
This Data class is the implementation of the GpgmeData objects.
Please see the information about __init__ for instantiation.

If no args are specified, make it an empty object.
If string alone is specified, initialize it with the data
contained there.
If file, offset, and length are all specified, file must
be either a filename or a file-like object, and the object
will be initialized by reading the specified chunk from the file.
If cbs is specified, it MUST be a tuple of the form:
(read_cb, write_cb, seek_cb, release_cb[, hook])
where the first four items are functions implementing reading,
writing, seeking the data, and releasing any resources once
the data object is deallocated. The functions must match the
following prototypes:
def read(amount, hook=None):
return
def write(data, hook=None):
return
def seek(offset, whence, hook=None):
return
def release(hook=None):
The functions may be bound methods. In that case, you can
simply use the 'self' reference instead of using a hook.
If file is specified without any other arguments, then
it must be a filename, and the object will be initialized from
that file.
