Description

__init__.__doc__

Initialize this PKCS#1 OAEP cipher object.
        
        :Parameters:
         key : an RSA key object
          If a private half is given, both encryption and decryption are possible.
          If a public half is given, only encryption is possible.
         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.
