b74ce8d948 bn/bn_exp.c: Solaris-specific fix, T4 MONTMUL relies on alloca. 2013-06-30 23:09:09 +02:00
Andy Polyakov
4ddacd9921 Optimize SPARC T4 MONTMUL support. 
Improve RSA sing performance by 20-30% by:
- switching from floating-point to integer conditional moves;
- daisy-chaining sqr-sqr-sqr-sqr-sqr-mul sequences;
- using MONTMUL even during powers table setup;

8a99cb29d1 Add secure DSA nonce flag. 
This change adds the option to calculate (EC)DSA nonces by hashing the
message and private key along with entropy to avoid leaking the private
key if the PRNG fails.

96a4c31be3 Ensure that, when generating small primes, the result is actually of the 
requested size. Fixes OpenSSL #2701.

This change does not address the cases of generating safe primes, or
where the |add| parameter is non-NULL.

7753a3a684 Add volatile qualifications to two blocks of inline asm to stop GCC from 
eliminating them as dead code.

Both volatile and "memory" are used because of some concern that the compiler
may still cache values across the asm block without it, and because this was
such a painful debugging session that I wanted to ensure that it's never
repeated.

361512da0d This commit completes recent modular exponentiation optimizations on 
x86_64 platform. It targets specifically RSA1024 sign (using ideas
from http://eprint.iacr.org/2011/239) and adds more than 10% on most
platforms. Overall performance improvement relative to 1.0.0 is ~40%
in average, with best result of 54% on Westmere. Incidentally ~40%
is average improvement even for longer key lengths.
