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 code n. The integer n 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 many 0 bytes as needed to fill the block.
