If a public half is given, only encryption is possible.

The hash function to use. This can be a module under `Crypto.Hash`

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 : byte string
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.
