Documentation
data Params
Represent Diffie Hellman parameters namely P (prime), and G (generator).
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
generate a private number with no specific property this number is usually called X in DH text.
calculatePublic :: Params -> PrivateNumber -> PublicNumber
calculate the public number from the parameters and the private key this number is usually called Y in DH text.
generatePublic :: Params -> PrivateNumber -> PublicNumber
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
generate a shared key using our private number and the other party public number
