+=head1 NAME
+
+ basecvt - radix conversion for arbitrary precision integers
+
+=head1 SYNOPSIS
+
+ basecvt <ibase> <obase> [values]
+
+=head1 DESCRIPTION
+
+The B<basecvt> program is a command-line tool for converting integers
+of arbitrary precision from one radix to another.  The current version
+supports radix values from 2 (binary) to 64, inclusive.  The first two
+command line arguments specify the input and output radix, in base 10.
+Any further arguments are taken to be integers notated in the input
+radix, and these are converted to the output radix.  The output is
+written, one integer per line, to standard output.
+
+When reading integers, only digits considered "valid" for the input
+radix are considered.  Processing of an integer terminates when an
+invalid input digit is encountered.  So, for example, if you set the
+input radix to 10 and enter '10ACF', B<basecvt> would assume that you
+had entered '10' and ignore the rest of the string.
+
+If no values are provided, no output is written, but the program
+simply terminates with a zero exit status.  Error diagnostics are
+written to standard error in the event of out-of-range radix
+specifications.  Regardless of the actual values of the input and
+output radix, the radix arguments are taken to be in base 10 (decimal)
+notation.
+
+=head1 DIGITS
+
+For radices from 2-10, standard ASCII decimal digits 0-9 are used for
+both input and output.  For radices from 11-36, the ASCII letters A-Z
+are also included, following the convention used in hexadecimal.  In
+this range, input is accepted in either upper or lower case, although
+on output only lower-case letters are used.
+
+For radices from 37-62, the output includes both upper- and lower-case
+ASCII letters, and case matters.  In this range, case is distinguished
+both for input and for output values.
+
+For radices 63 and 64, the characters '+' (plus) and '/' (forward
+solidus) are also used.  These are derived from the MIME base64
+encoding scheme.  The overall encoding is not the same as base64,
+because the ASCII digits are used for the bottom of the range, and the
+letters are shifted upward; however, the output will consist of the
+same character set.
+
+This input and output behaviour is inherited from the MPI library used
+by B<basecvt>, and so is not configurable at runtime.

+Division
+
+This describes the division algorithm used by the MPI library.
+
+Input:    a, b; a > b
+Compute:  Q, R; a = Qb + R
+
+The input numbers are normalized so that the high-order digit of b is
+at least half the radix.  This guarantees that we have a reasonable
+way to guess at the digits of the quotient (this method was taken from
+Knuth, vol. 2, with adaptations).
+
+To normalize, test the high-order digit of b.  If it is less than half
+the radix, multiply both a and b by d, where:
+
+             radix - 1
+	d = -----------
+              bmax + 1
+
+...where bmax is the high-order digit of b.  Otherwise, set d = 1.
+
+Given normalize values for a and b, let the notation a[n] denote the
+nth digit of a.  Let #a be the number of significant figures of a (not
+including any leading zeroes).
+
+	Let R = 0
+	Let p = #a - 1
+
+	while(p >= 0)
+	  do
+	    R = (R * radix) + a[p]
+	    p = p - 1
+	  while(R < b and p >= 0)
+
+	  if(R < b)
+	    break
+
+	  q = (R[#R - 1] * radix) + R[#R - 2]
+	  q = q / b[#b - 1]
+
+	  T = b * q
+
+	  while(T > L)
+	    q = q - 1
+	    T = T - b
+	  endwhile
+
+	  L = L - T
+
+	  Q = (Q * radix) + q
+
+	endwhile
+
+At this point, Q is the quotient, and R is the normalized remainder.
+To denormalize R, compute:
+
+	R = (R / d)
+
+At this point, you are finished.

+Exponentiation
+
+For exponentiation, the MPI library uses a simple and fairly standard
+square-and-multiply method.  The algorithm is this:
+
+Input:	a, b
+Output: a ** b
+
+	s = 1
+
+	while(b != 0)
+	  if(b is odd)
+	    s = s * a
+	  endif
+
+	  b = b / 2
+
+	  x = x * x
+	endwhile
+
+	return s
+
+The modular exponentiation is done the same way, except replacing:
+
+	s = s * a
+
+with
+	s = (s * a) mod m
+
+and replacing
+
+	x = x * x
+
+with
+
+	x = (x * x) mod m
+
+Here is a sample exponentiation using the MPI library, as compared to
+the same problem solved by the Unix 'bc' program on my system:
+
+Computation of 2,381,283 ** 235

+=head1 NAME
+
+ isprime - probabilistic primality testing
+
+=head1 SYNOPSIS
+
+ isprime <a>
+
+=head1 DESCRIPTION
+
+The B<isprime> program attempts to determine whether the arbitrary
+precision integer I<a> is prime.  It first tests I<a> for divisibility
+by the first 170 or so small primes, and assuming I<a> is not
+divisible by any of these, applies 15 iterations of the Rabin-Miller
+probabilistic primality test.
+
+If the program discovers that the number is composite, it will print:
+
+ Not prime (reason)
+
+Where I<reason> is either:
+
+	divisible by small prime x
+
+Or:
+
+	failed nth pseudoprime test
+
+In the first case, I<x> indicates the first small prime factor that
+was found.  In the second case, I<n> indicates which of the
+pseudoprime tests failed (numbered from 1)
+
+If this happens, the number is definitely not prime.  However, if the
+number succeeds, this message results:
+
+ Probably prime, 1 in 4^15 chance of false positive
+
+If this happens, the number is prime with very high probability, but
+its primality has not been absolutely proven, only demonstrated to a
+very convincing degree.
+
+The value I<a> can be input in standard decimal notation, or, if it is
+prefixed with I<Ox>, it will be read as hexadecimal.
+
+=head1 ENVIRONMENT
+
+You can control how many iterations of Rabin-Miller are performed on
+the candidate number by setting the I<RM_TESTS> environment variable
+to an integer value before starting up B<isprime>.  This will change
+the output slightly if the number passes all the tests.

+
+=head1 RESTRICTIONS
+
+This program is very slow, especially for large moduli.  It is
+intended as a way to help find primitive elements in a modular field,

+=head1 NAME
+
+ mpi-test - automated test program for MPI library
+
+=head1 SYNOPSIS
+
+ mpi-test <suite-name> [quiet]
+ mpi-test list
+ mpi-test help
+
+=head1 DESCRIPTION
+
+The B<mpi-test> program is a general unit test driver for the MPI
+library.  It is used to verify that the library works as it is
+supposed to on your architecture.  As with most such things, passing
+all the tests in B<mpi-test> does not guarantee the code is correct,
+but if any of them fail, there are certainly problems.
+
+Each major function of the library can be tested individually.  For a
+list of the test suites understood by B<mpi-test>, run it with the
+I<list> command line option:
+
+ mpi-test list
+
+This will display a list of the available test suites and a brief
+synopsis of what each one does.  For a brief overview of this
+document, run B<mpi-test> I<help>.
+
+B<mpi-test> exits with a zero status if the selected test succeeds, or
+a nonzero status if it fails.  If a I<suite-name> which is not
+understood by B<mpi-test> is given, a diagnostic is printed to the
+standard error, and the program exits with a result code of 2.  If a
+test fails, the result code will be 1, and a diagnostic is ordinarily

+Multiplication
+
+This describes the multiplication algorithm used by the MPI library.
+
+This is basically a standard "schoolbook" algorithm.  It is slow --
+O(mn) for m = #a, n = #b -- but easy to implement and verify.
+Basically, we run two nested loops, as illustrated here (R is the
+radix):
+
+k = 0
+for j <- 0 to (#b - 1)
+  for i <- 0 to (#a - 1)
+    w = (a[j] * b[i]) + k + c[i+j]
+    c[i+j] = w mod R
+    k = w div R
+  endfor
+  c[i+j] = k;
+  k = 0;
+endfor
+
+It is necessary that 'w' have room for at least two radix R digits.
+The product of any two digits in radix R is at most:
+
+	(R - 1)(R - 1) = R^2 - 2R + 1
+
+Since a two-digit radix-R number can hold R^2 - 1 distinct values,
+this insures that the product will fit into the two-digit register.
+
+To insure that two digits is enough for w, we must also show that
+there is room for the carry-in from the previous multiplication, and
+the current value of the product digit that is being recomputed.
+Assuming each of these may be as big as R - 1 (and no larger,
+certainly), two digits will be enough if and only if:
+
+	(R^2 - 2R + 1) + 2(R - 1) <= R^2 - 1
+
+Solving this equation shows that, indeed, this is the case:
+
+	R^2 - 2R + 1 + 2R - 2 <= R^2 - 1
+
+	R^2 - 1 <= R^2 - 1
+
+This suggests that a good radix would be one more than the largest
+value that can be held in half a machine word -- so, for example, as
+in this implementation, where we used a radix of 65536 on a machine
+with 4-byte words.  Another advantage of a radix of this sort is that
+binary-level operations are easy on numbers in this representation.
+
+Here's an example multiplication worked out longhand in radix-10,
+using the above algorithm:
+
+   a =     999
+   b =   x 999
+  -------------
+   p =   98001
+
+w = (a[jx] * b[ix]) + kin + c[ix + jx]
+c[ix+jx] = w % RADIX
+k = w / RADIX
+                                                               product
+ix	jx	a[jx]	b[ix]	kin	w	c[i+j]	kout	000000

+This file describes how pi is computed by the program in 'pi.c' (see
+the utils subdirectory).
+
+Basically, we use Machin's formula, which is what everyone in the
+world uses as a simple method for computing approximations to pi.
+This works for up to a few thousand digits without too much effort.
+Beyond that, though, it gets too slow.
+
+Machin's formula states:
+
+	 pi := 16 * arctan(1/5) - 4 * arctan(1/239)
+
+We compute this in integer arithmetic by first multiplying everything
+through by 10^d, where 'd' is the number of digits of pi we wanted to
+compute.  It turns out, the last few digits will be wrong, but the
+number that are wrong is usually very small (ordinarly only 2-3).
+Having done this, we compute the arctan() function using the formula:
+
+                       1      1       1       1       1     
+       arctan(1/x) := --- - ----- + ----- - ----- + ----- - ...
+                       x    3 x^3   5 x^5   7 x^7   9 x^9
+
+This is done iteratively by computing the first term manually, and
+then iteratively dividing x^2 and k, where k = 3, 5, 7, ... out of the
+current figure.  This is then added to (or subtracted from) a running
+sum, as appropriate.  The iteration continues until we overflow our
+available precision and the current figure goes to zero under integer
+division.  At that point, we're finished.
+
+Actually, we get a couple extra bits of precision out of the fact that
+we know we're computing y * arctan(1/x), by setting up the multiplier
+as:
+
+      y * 10^d
+
+... instead of just 10^d.  There is also a bit of cleverness in how
+the loop is constructed, to avoid special-casing the first term.
+Check out the code for arctan() in 'pi.c', if you are interested in
+seeing how it is set up.
+
+Thanks to Jason P. for this algorithm, which I assembled from notes
+and programs found on his cool "Pile of Pi Programs" page, at:
+
+      http://www.isr.umd.edu/~jasonp/pipage.html
+
+Thanks also to Henrik Johansson <Henrik.Johansson@Nexus.Comm.SE>, from
+whose pi program I borrowed the clever idea of pre-multiplying by x in
+order to avoid a special case on the loop iteration.

+=head1 NAME
+
+ prng - pseudo-random number generator
+
+=head1 SYNOPSIS
+
+ prng [count]
+
+=head1 DESCRIPTION
+
+B<Prng> generates 32-bit pseudo-random integers using the
+Blum-Blum-Shub (BBS) quadratic residue generator.  It is seeded using
+the standard C library's rand() function, which itself seeded from the
+system clock and the process ID number.  Thus, the values generated
+are not particularly useful for cryptographic applications, but they
+are in general much better than the typical output of the usual
+multiplicative congruency generator used by most runtime libraries.
+
+You may optionally specify how many random values should be generated
+by giving a I<count> argument on the command line.  If you do not
+specify a count, only one random value will be generated.  The results
+are output to the standard output in decimal notation, one value per
+line.
+
+=head1 RESTRICTIONS
+
+As stated above, B<prng> uses the C library's rand() function to seed
+the generator, so it is not terribly suitable for cryptographic
+applications.  Also note that each time you run the program, a new
+seed is generated, so it is better to run it once with a I<count>
+parameter than it is to run it multiple times to generate several
+values.

+Modular Reduction
+
+Usually, modular reduction is accomplished by long division, using the
+mp_div() or mp_mod() functions.  However, when performing modular
+exponentiation, you spend a lot of time reducing by the same modulus
+again and again.  For this purpose, doing a full division for each
+multiplication is quite inefficient.
+
+For this reason, the mp_exptmod() function does not perform modular
+reductions in the usual way, but instead takes advantage of an
+algorithm due to Barrett, as described by Menezes, Oorschot and
+VanStone in their book _Handbook of Applied Cryptography_, published
+by the CRC Press (see Chapter 14 for details).  This method reduces
+most of the computation of reduction to efficient shifting and masking
+operations, and avoids the multiple-precision division entirely.
+
+Here is a brief synopsis of Barrett reduction, as it is implemented in
+this library.
+
+Let b denote the radix of the computation (one more than the maximum
+value that can be denoted by an mp_digit).  Let m be the modulus, and
+let k be the number of significant digits of m.  Let x be the value to
+be reduced modulo m.  By the Division Theorem, there exist unique
+integers Q and R such that:
+
+	 x = Qm + R, 0 <= R < m
+
+Barrett reduction takes advantage of the fact that you can easily
+approximate Q to within two, given a value M such that:
+
+	                  2k
+	                 b
+	    M = floor( ----- )
+	                 m
+
+Computation of M requires a full-precision division step, so if you
+are only doing a single reduction by m, you gain no advantage.
+However, when multiple reductions by the same m are required, this
+division need only be done once, beforehand.  Using this, we can use
+the following equation to compute Q', an approximation of Q:
+
+                     x
+            floor( ------ ) M
+                      k-1
+                     b
+Q' = floor( ----------------- )
+                    k+1
+                   b
+
+The divisions by b^(k-1) and b^(k+1) and the floor() functions can be
+efficiently implemented with shifts and masks, leaving only a single
+multiplication to be performed to get this approximation.  It can be
+shown that Q - 2 <= Q' <= Q, so in the worst case, we can get out with
+two additional subtractions to bring the value into line with the
+actual value of Q.
+
+Once we've got Q', we basically multiply that by m and subtract from
+x, yielding:
+
+   x - Q'm = Qm + R - Q'm
+
+Since we know the constraint on Q', this is one of:
+
+      R
+      m + R
+      2m + R
+
+Since R < m by the Division Theorem, we can simply subtract off m
+until we get a value in the correct range, which will happen with no
+more than 2 subtractions:
+
+     v = x - Q'm
+
+     while(v >= m)
+       v = v - m
+     endwhile
+
+
+In random performance trials, modular exponentiation using this method
+of reduction gave around a 40% speedup over using the division for
+reduction.

+Square Root
+
+A simple iterative algorithm is used to compute the greatest integer
+less than or equal to the square root.  Essentially, this is Newton's
+linear approximation, computed by finding successive values of the
+equation:
+
+		    x[k]^2 - V
+x[k+1]	 =  x[k] - ------------
+	             2 x[k]
+
+...where V is the value for which the square root is being sought.  In
+essence, what is happening here is that we guess a value for the
+square root, then figure out how far off we were by squaring our guess
+and subtracting the target.  Using this value, we compute a linear
+approximation for the error, and adjust the "guess".  We keep doing
+this until the precision gets low enough that the above equation
+yields a quotient of zero.  At this point, our last guess is one
+greater than the square root we're seeking.
+
+The initial guess is computed by dividing V by 4, which is a heuristic
+I have found to be fairly good on average.  This also has the
+advantage of being very easy to compute efficiently, even for large
+values.
+
+So, the resulting algorithm works as follows:
+
+    x = V / 4   /* compute initial guess */
+    
+    loop
+	t = (x * x) - V   /* Compute absolute error  */
+	u = 2 * x         /* Adjust by tangent slope */
+	t = t / u
+
+	/* Loop is done if error is zero */
+	if(t == 0)
+	    break
+
+	/* Adjust guess by error term    */
+	x = x - t
+    end
+
+    x = x - 1
+
+The result of the computation is the value of x.

+Squaring Algorithm
+
+When you are squaring a value, you can take advantage of the fact that
+half the multiplications performed by the more general multiplication
+algorithm (see 'mul.txt' for a description) are redundant when the
+multiplicand equals the multiplier.
+
+In particular, the modified algorithm is:
+
+k = 0
+for j <- 0 to (#a - 1)
+  w = c[2*j] + (a[j] ^ 2);
+  k = w div R
+
+  for i <- j+1 to (#a - 1)
+    w = (2 * a[j] * a[i]) + k + c[i+j]
+    c[i+j] = w mod R
+    k = w div R
+  endfor
+  c[i+j] = k;
+  k = 0;
+endfor
+
+On the surface, this looks identical to the multiplication algorithm;
+however, note the following differences:
+
+  - precomputation of the leading term in the outer loop
+
+  - i runs from j+1 instead of from zero
+
+  - doubling of a[i] * a[j] in the inner product
+
+Unfortunately, the construction of the inner product is such that we
+need more than two digits to represent the inner product, in some
+cases.  In a C implementation, this means that some gymnastics must be
+performed in order to handle overflow, for which C has no direct
+abstraction.  We do this by observing the following:
+
+If we have multiplied a[i] and a[j], and the product is more than half
+the maximum value expressible in two digits, then doubling this result
+will overflow into a third digit.  If this occurs, we take note of the
+overflow, and double it anyway -- C integer arithmetic ignores
+overflow, so the two digits we get back should still be valid, modulo
+the overflow.
+
+Having doubled this value, we now have to add in the remainders and
+the digits already computed by earlier steps.  If we did not overflow
+in the previous step, we might still cause an overflow here.  That
+will happen whenever the maximum value expressible in two digits, less
+the amount we have to add, is greater than the result of the previous
+step.  Thus, the overflow computation is:
+
+
+  u = 0
+  w = a[i] * a[j]
+
+  if(w > (R - 1)/ 2)
+    u = 1;
+
+  w = w * 2
+  v = c[i + j] + k
+
+  if(u == 0 && (R - 1 - v) < w)
+    u = 1
+
+If there is an overflow, u will be 1, otherwise u will be 0.  The rest
+of the parameters are the same as they are in the above description.

+Timings are given in seconds, computed using the C library's clock()
+function.  The first column gives the hardware and compiler
+configuration used for the test. The second column indicates the
+number of tests that were aggregated to get the statistics for that
+size.  These were compiled using 16 bit digits.
+
+Source data were generated randomly using a fixed seed, so they should
+be internally consistent, but may vary on different systems depending
+on the C library.  Also, since the resolution of the timer accessed by
+clock() varies, there may be some variance in the precision of these
+measurements.
