def new(key, hashAlgo=None, mgfunc=None, label=b'') 

Description

new.__doc__

Return a cipher object `PKCS1OAEP_Cipher` that can be used to perform PKCS#1 OAEP encryption or decryption.

    :Parameters:
     key : RSA key object
      The key to use to encrypt or decrypt the message. This is a `Crypto.PublicKey.RSA` object.
      Decryption is only possible if *key* is a private RSA key.
     hashAlgo : hash object
      The hash function to use. This can be a module under `Crypto.Hash`
      or an existing hash object created from any of such modules. If not specified,
      `Crypto.Hash.SHA` (that is, SHA-1) is used.
     mgfunc : callable
      A mask generation function that accepts two parameters: a string to
      use as seed, and the lenth of the mask to generate, in bytes.
      If not specified, the standard MGF1 is used (a safe choice).
     label : string
      A label to apply to this particular encryption. If not specified,
      an empty string is used. Specifying a label does not improve
      security.
 
    :attention: Modify the mask generation function only if you know what you are doing.
      Sender and receiver must use the same one.
