Synopsis
type Octet = Word8
msb :: Int
fromTwosComp :: Integral a => [Octet] -> a
toTwosComp :: Integral a => a -> [Octet]
toOctets :: (Integral a, Integral b) => a -> b -> [Octet]
fromOctets :: (Integral a, Integral b) => a -> [Octet] -> b
i2osp :: Integral a => Int -> a -> [Octet]
Types and Constants
type Octet = Word8
The basic type for encoding and decoding.
msb :: Int
The most significant bit of an Octet.
Octet Conversion Functions
fromTwosComp :: Integral a => [Octet] -> a
Convert from twos complement.
toTwosComp :: Integral a => a -> [Octet]
toOctets :: (Integral a, Integral b) => a -> b -> [Octet]
Take a number a convert it to base n as a list of octets.
fromOctets :: (Integral a, Integral b) => a -> [Octet] -> b
Take a list of octets (a number expressed in base n) and convert it to a number.
i2osp :: Integral a => Int -> a -> [Octet]
Take the length of the required number of octets and convert the number to base 256 padding it out to the required length. If the required length is less than the number of octets of the converted number then return the converted number. NB this is different from the standard ftp://ftp.rsasecurity.com/pub/pkcs/pkcs-1/pkcs-1v2-1.pdf but mimics how replicate behaves.
