# While original submission covers 512- and 1024-bit exponentiation,
|
||
|
|
# this module is limited to 512-bit version only (and as such
|
||
|
|
# accelerates RSA1024 sign). This is because improvement for longer
|
||
|
|
# keys is not high enough to justify the effort, highest measured
|
||
|
|
# was ~5% on Westmere. [This is relative to OpenSSL 1.0.2, upcoming
|
||
|
|
# for the moment of this writing!] Nor does this module implement
|
||
|
|
# "monolithic" complete exponentiation jumbo-subroutine, but adheres
|
||
|
|
# to more modular mixture of C and assembly. And it's optimized even
|
||
|
|
# for processors other than Intel Core family (see table below for
|
||
|
|
# improvement coefficients).
