Description:
 def encrypt(self, data, *recipients, **kwargs):
 """Encrypt the message contained in ``data`` to ``recipients``. :param str data: The file or bytestream to encrypt. :param str recipients: The recipients to encrypt to. Recipients must be specified keyID/fingerprint. Care should be taken in Python2.x to make sure that the given fingerprint is in fact a string and not a unicode object. Multiple recipients may be specified by doing ``GPG.encrypt(data, fpr1, fpr2, fpr3)`` etc. :param str default_key: The keyID/fingerprint of the key to use for signing. If given, ``data`` will be encrypted and signed. :param str passphrase: If given, and ``default_key`` is also given, use this passphrase to unlock the secret portion of the ``default_key`` to sign the encrypted ``data``. Otherwise, if ``default_key`` is not given, but ``symmetric=True``, then use this passphrase as the passphrase for symmetric encryption. Signing and symmetric encryption should *not* be combined when sending the ``data`` to other recipients, else the passphrase to the secret key would be shared with them. :param bool armor: If True, ascii armor the output; otherwise, the output will be in binary format. (Default: True) :param bool encrypt: If True, encrypt the ``data`` using the ``recipients`` public keys. (Default: True) :param bool symmetric: If True, encrypt the ``data`` to ``recipients`` using a symmetric key. See the ``passphrase`` parameter. Symmetric encryption and public key encryption can be used simultaneously, and will result in a ciphertext which is decryptable with either the symmetric ``passphrase`` or one of the corresponding private keys. :param bool always_trust: If True, ignore trust warnings on recipient keys. If False, display trust warnings. (default: True) :param str output: The output file to write to. If not specified, the encrypted output is returned, and thus should be stored as an object in Python. For example: 'The crow flies at midnight.' :param bool throw_keyids: If True, make all **recipients** keyids be zero'd out in packet information. This is the same as using **hidden_recipients** for all **recipients**. (Default: False). :param list hidden_recipients: A list of recipients that should have their keyids zero'd out in packet information. :param str cipher_algo: The cipher algorithm to use. To see available algorithms with your version of GnuPG, do: :command:`$ gpg --with-colons --list-config ciphername`. The default ``cipher_algo``, if unspecified, is ``'AES256'``. :param str digest_algo: The hash digest to use. Again, to see which hashes your GnuPG is capable of using, do: :command:`$ gpg --with-colons --list-config digestname`. The default, if unspecified, is ``'SHA512'``. :param str compress_algo: The compression algorithm to use. Can be one of ``'ZLIB'``, ``'BZIP2'``, ``'ZIP'``, or ``'Uncompressed'``. .. seealso:: :meth:`._encrypt` """
