By using several contexts you can run several cryptographic operations in parallel, with different configuration. Access to a context must be synchronized.

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) Returns: -- an object describing the result of the key creation Raises: GPGMEError -- as signaled by the underlying library r] Nc s � S )Nr )r^ r_ r` ra )rb r r rc 5 s z)Context.create_key.<locals>.passphrase_cbr r )N)r � is_a_stringrR r r rg rh Z op_createkey�create�SIGN�ENCRZCERT�AUTH�NOPASSWD�NOEXPIREZFORCE�op_genkey_result)r Zuserid� algorithm� expires_in�expiresro ru Zcertify� authenticaterb �forcerr rs rc r )rb r � create_key� s( ; b zContext.create_keyc s� t j� �r<| j} t| dd�} tj| _d� fdd� } | j| � zf| j||d||rVtjj nd|rdtjj ndB |rttjj ndB � dkr�tjj ndB |r�dntjj B � W dt j� �r�| | _| r�| j| dd� � X | j� S )a@ Create a subkey 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.

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.

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 <a b"bytes" object> def write(data, hook=None): return <the number of bytes written> def seek(offset, whence, hook=None): return <the new file position> def release(hook=None): <return value and exceptions are ignored> 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.
