Synopsis

- encode :: (([Octet] -> [Octet]) -> [Octet] -> Int -> [Octet]) -> ([Octet] -> [Octet]) -> [Octet] -> [Octet] -> [Octet] -> [Octet] -> [Octet]
- decode :: (([Octet] -> [Octet]) -> [Octet] -> Int -> [Octet]) -> ([Octet] -> [Octet]) -> [Octet] -> [Octet] -> [Octet]

# Function Types

encode :: (([Octet] -> [Octet]) -> [Octet] -> Int -> [Octet]) -> ([Octet] -> [Octet]) -> [Octet] -> [Octet] -> [Octet] -> [Octet] -> [Octet]

Take a mask generating function, a hash function, a label (which may be null), a random seed, the modulus of the key and the message and returns an encoded message. NB you could pass in the length of the modulus but it seems safer to pass in the modulus itself and calculate the length when required. See ftp://ftp.rsasecurity.com/pub/pkcs/pkcs-1/pkcs-1v2-1.pdf for more details.

decode :: (([Octet] -> [Octet]) -> [Octet] -> Int -> [Octet]) -> ([Octet] -> [Octet]) -> [Octet] -> [Octet] -> [Octet]

Take a mask generating function, a hash function, a label (which may be null) and the message and returns the decoded.
