Re: Proving RC6' quadratic permutation is a permutation

RC6 is a block cipher. "×" is a common symbol for multiplication.

I've been doing multiplication for close to 50 years now, and I've
never seen that symbol used for it or anything else. Maybe it looks
different to you than to me - to me, it's diamond-shaped.

My earlier messages contain these MIME headers:

Mime-Version: 1.0
Content-Type: text/plain; charset=iso-8859-1
Content-Transfer-Encoding: 8bit

It's then up to your favourite proper newsreader to parse this and
conclude that the message body is 8-bit ISO-8859-1 and decode it.

I'm formatting my current message in UTF-8 on purpose. If your
client now shows the sign properly, it is MIME-challenged and should
be repaired or erased. After all, the MIME standard covering this has
already become ten years of age.

The character has the octet value 0xD7, which you can take a look at
here: <URL: http://en.wikipedia.org/wiki/Iso-8859-1#Code_table >

If it fails to show up in Wikipedia as well, your font(s) are probably
not set up correctly.

The Unicode name for this character is, according to gucharmap,
"MULTIPLICATION SIGN". :-)


HTH.

ć (Random character outside ISO-8859-1 to trick Gnus into posting with
UTF-8, nothing to worry about.)
