[osflash] Porting SHA-1 implementation from Java to AS3

[Tiago Vale]

Hi list,

Im porting a SHA-1 implementation from java to AS3 and theres a strange
behaviour that I cant deal with, I really dont know if this is a Java or a
Flash question, but here it goes.


JAVA

tracing "int " + blk + " + " +  0x5A827999 + " + " + ro + " + " + prev+   "
= " + data[z]

output  int -67371266 + 1518500249 + 585074272 + 271733878 = -1987030163


FLEX
tracing "int " + blk + " + " +  0x5A827999 + " + " + ro + " + " + prev+   "
= " + data[z]

output  int -67371266 + 1518500249 + 585074272 + 271733878 = 2307937133

I know some arithematics enough to know that a first glance Flex is dealing
right, but since this implementation works with Java I reall whant to know
whats wrongh here.

this is happening in the R0 function.


Thankz in advance
