Arguments

:: MonadRandom m 
=> Int

number of bits

-> Integer

generator

-> m Params 

generate params from a specific generator (2 or 5 are common values) we generate a safe prime (a prime number of the form 2p+1 where p is also prime)

generatePrivate :: MonadRandom m => Params -> m PrivateNumber Source #

generate a private number with no specific property this number is usually called X in DH text.

calculatePublic :: Params -> PrivateNumber -> PublicNumber Source #

calculate the public number from the parameters and the private key this number is usually called Y in DH text.

generatePublic :: Params -> PrivateNumber -> PublicNumber Source #

calculate the public number from the parameters and the private key this number is usually called Y in DH text.

DEPRECATED use calculatePublic

getShared :: Params -> PrivateNumber -> PublicNumber -> SharedKey Source #

generate a shared key using our private number and the other party public number
