; MD5 hash generator -- Paul Houle (paulhoule.com) 11/13/2017
|
||||
;
|
||||
; Called only from phmd5.c -- see phmd5.h for overview
|
||||
;
|
||||
; This is the same logic in phmd5a.asm, implemented (after the fact) in C.
|
||||
; The C compiler must support the "_rotl()" function generated inline to
|
||||
; achieve maximal performance.
|
||||
;
|
||||
; It turns out the MSFT C compiler, coupled with newer processor, results
|
||||
; in timings comparable to the 32-bit only phmd5a.asm hand-written assembly.
|
||||
; Therefore this "C" implementation is now used.
|
||||
; Avoiding assembly allows the code to be compiled either 32 or 64 bit.
|
||||
;
|
||||
; Note that a "little-endian" memory architecture is assumed.
|
||||
;
|
||||
; The Fx() and MD5STEP() macros were written by Colin Plumb in 1993.
|
||||
; MD5STEP() was changed slightly to match how phmd5a.asm operates.
