16349eeceb Port X931 key generation routines from FIPS branch. Don't include deprecated 
versions as they weren't in 0.9.8 before now anyway.

c3031a4610 Avoid BN_MONT_CTX incompatibility. 2008-05-02 18:47:19 +00:00

812d8a176c Unobtrusive backport of 32-bit x86 Montgomery improvements from 0.9.9-dev: 
you need to use "enable-montasm" to see a difference.  (Huge speed
advantage, but BN_MONT_CTX is not binary compatible, so this can't be
enabled by default in the 0.9.8 branch.)

The CHANGES entry also covers the 64-bit x86 backport in November 2007
by appro.
