Functions

func GeneratePaillier 

func GeneratePaillier(rand io.Reader) (*paillier.PrivateKey, error)

func GeneratePreParamsWithContextAndRandom 

func GeneratePreParamsWithContextAndRandom(ctx context.Context, rand io.Reader, optionalConcurrency ...int) (*paillier.PrivateKey, error)

GeneratePreParams finds two safe primes and computes the Paillier secret required for the protocol. This can be a time consuming process so it is recommended to do it out-of-band. If not specified, a concurrency value equal to the number of available CPU cores will be used. If pre-parameters could not be generated before the context is done, an error is returned.
