    Computes the product of several exponentiations of the same base and distinct exponents.

    Computes the product of several exponentiations of the same base and distinct exponents. An optimization is used to compute it more quickly by keeping in memory the result of h1, h2, h4,h8,... and using it in the calculation.

    Note that if we want a one-time exponentiation of h it is preferable to use the basic exponentiation function since there is no point to keep anything in memory if we have no intention to use it.

    returns

    the exponentiation result

    This function returns the value <I>k</I> which is the maximum length of a string to be encoded to a Group Element of this group.

    This function returns the value <I>k</I> which is the maximum length of a string to be encoded to a Group Element of this group.

    Any string of length <I>k</I> has a numeric value that is less than (p-1)/2 - 1. <I>k</I> is the maximum length a binary string is allowed to be in order to encode the said binary string to a group element and vice-versa.

    If a string exceeds the <I>k</I> length it cannot be encoded.

    returns

    k the maximum length of a string to be encoded to a Group Element of this group. k can be zero if there is no maximum.
