Hello,
I am trying to encrypt and decrypt a string using the RSA encryption algorithm from http://cypherspace.org/~adam/rsa/story.html.
I am using the pure Perl version and following the instructions exactly as printed. Yet it doesn't work. The algorithm is:
do 'bigint.pl';($_,$n)=@ARGV;s/^.(..)*$/0$&/;($k=unpack('B*',pack('H*'
+,$_)))=~
s/^0*//;$x=0;$z=$n=~s/./$x=&badd(&bmul($x,16),hex$&)/ge;while(read(STD
+IN,$_,$w
=((2*$d-1+$z)&~1)/2)){$r=1;$_=substr($_."\0"x$w,$c=0,$w);s/.|\n/$c=&ba
+dd(&bmul
($c,256),ord$&)/ge;$_=$k;s/./$r=&bmod(&bmul($r,$r),$x),$&?$r=&bmod(&bm
+ul($r,$c
),$x):0,""/ge;($r,$t)=&bdiv($r,256),$_=pack(C,$t).$_ while$w--+1-2*$d;
+print}

Is there an issue with Win32 and this code?

Thanks
