data PublicNumber Source #
Represent Diffie Hellman public number Y.
Instances
data PrivateNumber Source #
Represent Diffie Hellman private number X.
Instances
generateParams :: CPRG g => g -> Int -> Integer -> (Params, g) Source #
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 :: CPRG g => g -> Params -> (PrivateNumber, g) 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
