Yay!  It's officially non-exportable.  It would be kind of fun to
observe a lawsuit built around someone in the US using this as a .sig:

: Have *you* exported RSA today? --> http://www.dcs.ex.ac.uk/~aba/rsa/
: 
: print pack"C*",split/\D+/,`echo "16iII*o\U@{$/=$z;[(pop,pop,unpack"H*",<>
: )]}\EsMsKsN0[lN*1lK[d2%Sa2/d0<X+d*lMLa^*lN%0]dsXx++lMlN/dsM0<J]dsJxp"|dc`
 
Perhaps they should round up all those who have used it in the past as
a .sig and lock them up.

I must admit to being very curious as to how html links can be an
export.

Is this an export?

	<A HREF="http://www.dcs.ex.ac.uk/~aba/rsa/">RSA .sig</A>

Is this?

	<A HREF="http://www.ifi.uio.no/pgp5i.tar.gz">PGP 5.0i</A>

(guessing URL).

This one might be fun also, but still I can't see that it's an export:

	<IMG SRC="http://www.dcs.ex.ac.uk/~aba/shirt/rsa.gif">

(it's an inline image of the RSA .sig).

Weird so this is exportable (otp.c):

main(i,c)int*c;{for(c=fopen(c[1],"r");i=~getchar();putchar(getc(c)^~i));}

Here's a perl one too btw:

open P,shift;read(P,$p,length),print $_^$p while<>
