f4681b0864 Use uniformly chosen witnesses for Miller-Rabin test 
(by using new BN_pseudo_rand_range function)

98486a9310 improved bignum test as in 0.9.7. 
We need this to find out if the bignum failures on Irix and Alpha are
caused by new 0.9.7 code or just aren't triggered in the 0.9.6 test suite.

418a0d151e Simplify BN_rand_range 2001-02-10 00:34:20 +00:00

07fc72fea1 Integrate my implementation of a countermeasure against 
Bleichenbacher's DSA attack.  With this implementation, the expected
number of iterations never exceeds 2.

New semantics for BN_rand_range():
BN_rand_range(r, min, range) now generates r such that
     min <= r < min+range.
(Previously, BN_rand_range(r, min, max) generated r such that
     min <= r < max.
It is more convenient to have the range; also the previous
prototype was misleading because max was larger than
the actual maximum.)

fe772376ec Don't allow BIGNUMs to become so large that computations with dmax

9b141126d4 New functions BN_CTX_start(), BN_CTX_get(), BN_CTX_end() to access 
temporary BIGNUMs. BN_CTX still uses a fixed number of BIGNUMs, but
the BN_CTX implementation could now easily be changed.

generating DSA primes (why not use BN_is_prime()?)

6d31193858 Complete rewrite of the error code generation script. It now runs as a single 
script, translates function codes better and doesn't need the K&R function
prototypes to work (NB. the K&R prototypes can't be wiped just yet: they are
still needed by the DEF generator...). I also ran the script with the -rewrite
option to update all the header and source files.
