Method Detail

hash

public GroupElement hash(byte[] x)

Description copied from interface: HashIntoStructure

Hashes a byte array into the structure.

Specified by:

hash in interface HashIntoGroup

hash in interface HashIntoStructure

Parameters:

x - a sequence of bytes to hash

Returns:

the resulting structure element

getRepresentation

public Representation getRepresentation()

Description copied from interface: Representable

The representation of this object. Used for serialization. A convenient way to implement this is using @link ReprUtil

Specified by:

getRepresentation in interface Representable

Returns:

a Representation or null if an equal object can be recreated without any information.
