Module Cryptokit.Padding
The Padding
module defines a generic interface for padding input data to an integral number of blocks, as well as two popular padding schemes.
class type scheme = object ... end
Generic interface of a padding scheme.
val length : scheme
This padding scheme pads data with
n
copies of the character having coden
. The integern
lies between 1 and the block size (included). This constraint ensures non-ambiguity. This scheme is defined in RFC 2040 and in PKCS 5 and 7.
val _8000 : scheme
This padding scheme pads data with one
0x80
byte, followed by as many0
bytes as needed to fill the block.
