Args: private_key (byte string): The private key encoded in binary form. The actual encoding is algorithm specific. In most cases, it is DER. key_oid (string): The object identifier (OID) of the private key to wrap. It is a dotted string, like ``1.2.840.113549.1.1.1`` (for RSA keys). passphrase (bytes string or string): The secret passphrase from which the wrapping key is derived. Set it only if encryption is required. protection (string): The identifier of the algorithm to use for securely wrapping the key. The default value is ``PBKDF2WithHMAC-SHA1AndDES-EDE3-CBC``. prot_params (dictionary): Parameters for the protection algorithm. +------------------+-----------------------------------------------+ | Key | Description | +==================+===============================================+ | iteration_count | The KDF algorithm is repeated several times to| | | slow down brute force attacks on passwords | | | (called *N* or CPU/memory cost in scrypt). | | | The default value for PBKDF2 is 1000. | | | The default value for scrypt is 16384. | +------------------+-----------------------------------------------+ | salt_size | Salt is used to thwart dictionary and rainbow | | | attacks on passwords.

If ``None``, no ``parameters`` field will be added. By default, the ASN.1 type ``NULL`` is used. randfunc (callable): Random number generation function; it should accept a single integer N and return a string of random data, N bytes long. If not specified, a new RNG will be instantiated from :mod:`Crypto.Random`. Return: The PKCS#8-wrapped private key (possibly encrypted), as a byte string.
