  de.cscc.crypto.util.ByteUtil

public final class ByteUtil

extends Object

ByteUtil Class. Class that holds only static methods to convert bytes and byte arrays to Strings. These Strings holds the hex or binary representation of the converted byte or byte arrays. This class can't be instance, because its constructor is private.
