Seal class
A wrapper for the Microsoft SEAL library.
Extends Afhe and provides additional functionalities specific to Microsoft SEAL.
Constructors
- Seal(String scheme)
- Creates a new instance of the SEAL backend with a given scheme.
- Seal.noScheme()
- Creates a new instance of the SEAL backend without a scheme.
