38e33cef15 Document DSA and SHA. 
New function BN_pseudo_rand().
Use BN_prime_checks_size(BN_num_bits(w)) rounds of Miller-Rabin when
generating DSA primes (why not use BN_is_prime()?)

b25c8db872 AFAICS lst1 stands for "lshift test" not "list". 2000-01-21 00:00:12 +00:00

0c50e02b30 - Pseudo-seed the PRNG in programs used for "make test" 
because otherwise BN_rand will fail unless DEVRANDOM works,
  which causes the programs to dump core because they
  don't check the return value of BN_rand (and if they
  did, we still couldn't test anything).

- add comment to some files that appear not to be used at all.

eb952088f0 Precautions against using the PRNG uninitialized: RAND_bytes() now 
returns int (1 = ok, 0 = not seeded). New function RAND_add() is the
same as RAND_seed() but takes an estimate of the entropy as an additional
argument.

76aa0ddc86 Turn BN_prime_checks into a macro. 
Primes p where (p-1)/2 is prime too are called "safe", not "strong".

ce2c95b2a2 Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD). The 
problem was that one of the replacement routines had not been working since
SSLeay releases.  For now the offending routine has been replaced with
non-optimised assembler.  Even so, this now gives around 95% performance
improvement for 1024 bit RSA signs.

4c22909e31 Extra i386+gcc bn_div.c tune-up featuring inline division and saving 
the remainder left in %edx. Here is the resulting performance improvement
matrix (improvement as a result of this *and* previous tune-up committed
two days ago). The results were obtained by profiling the "div" part of
the crypto/bn/bnspeed.c.

CPU	BN_div	bn_div_words	overall	comment
------------------------------------------------------------------------
PII	+16%	accumulated by	+2-3%	PII multiplies damn fast! Taking
		inlining		multiplication out of the loop
					didn't make too much difference.
					Eliminating of the multiplication
					involved in remainder calculation
					is the major factor.

Pentium	+45%	accumulated by	+7-9%	mull isn't that fast and replacing
		inlining		multiplications with additions in
					the loop has more visible effect:-)

MIPS	+75%	+12%		+20-25%	In addition to the taking mults
R10000					out of the loop (giving 12% in the
					asm/mips3.s) three mults were
					eliminated in BN_div.

Alpha	+30%	+50%		+10-15%	Same as above. But remember that
EV4					bn_div_words is a C implementation.
					It takes 4 Alpha mults in C to do
					the same thing as 1 MIPS mult in
					assembler does. So the effect (50%)
					is more impressive. But not the
					overall one... Well, if Alpha
					bn_mul_add would be implemented
					in assembler overall improvement
					would be closer to MIPS...

0dd25e3606 Bignum division tune-up. Idea is to move multiplications in front of 
loop body and replace 'em with addition/subtraction.
