Args: private_key (bytes): 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) or ``'1.2.840.10045.2.1'`` (for ECC keys). Keyword Args: passphrase (bytes 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. Refer to :ref:`the encryption parameters` . The default value is ``'PBKDF2WithHMAC-SHA1AndDES-EDE3-CBC'``. prot_params (dictionary): Parameters for the key derivation function (KDF). Refer to :ref:`the encryption parameters` . key_params (DER object or None): The ``parameters`` field to use in the ``AlgorithmIdentifier`` SEQUENCE. 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`. Returns: bytes: The PKCS#8-wrapped private key (possibly encrypted). rzEmpty passphrasez"PBKDF2WithHMAC-SHA1AndDES-EDE3-CBC)rrrencode ValueErrortobytesr encrypt) private_keykey_oid passphrase protection prot_params key_paramsrandfunc algorithmpk_info pk_info_ders Q/var/www/html/Resume-Scraper/venv/lib/python3.12/site-packages/Crypto/IO/PKCS8.pyr r 2sjW!5 67 W!5z BC {+G .."K +,,$J9 ==j#[( <<c|Qt|}d} tj||}d}|s t j||}d}|st dztj|d }t|d k(r |s t d |d d k(rt|dvr6t d|d dk(rt|dvrt dt dtj|dd }tj|d j}t|dk(rd}n tj|dd}tj|d j} || |fS#t$r}dt |z}Yd}~hd}~wt $rd}YywxYw#t$r}dt |zz }Yd}~d}~wt $r dz }YwxYw#|d}YxYw)aNUnwrap a private key from a PKCS#8 blob (clear or encrypted).
