SYNOPSIS
	   use Crypt::DSA::Util qw( func1 func2 ... );

DESCRIPTION
       Crypt::DSA::Util contains a set of exportable utility functions used through the Crypt::DSA set of libraries.

   bitsize($n)
       Returns the number of bits in the Math::Pari integer object $n.

   bin2mp($string)
       Given a string $string of any length, treats the string as a base-256 representation of an integer, and returns that integer, a Math::Pari
       object.

   mp2bin($int)
       Given a biginteger $int (a Math::Pari object), linearizes the integer into an octet string, and returns the octet string.

   mod_exp($a, $exp, $n)
       Computes $a ^ $exp mod $n and returns the value. The calculations are done using Math::Pari, and the return value is a Math::Pari object.

   mod_inverse($a, $n)
       Computes the multiplicative inverse of $a mod $n and returns the value. The calculations are done using Math::Pari, and the return value is
       a Math::Pari object.
