Welcome to the sci.crypt sandbox. This is a place where new cipher designs can
be posted without annoying the readership of the sci.crypt newsgroup. For those
who are more cryptanalytically inclined, this is a place to read about, and try
out, various techniques. Until I get a (semi) automatic submission script going,
just email me with any designs/breaks. Please read the
the rules first! Also of interest may be the way
that I'm scoring the ciphers(updated 2-May-04).
This is, like the rest of the site, highly subject to change.
Note that if you want to contact me, you will either have to have
javascript turned on, or demangle my email address (replace
"where.you.got.this.from" with "emboss.co.nz"). Also contact me if the site
looks horribly broken to your browser (the disappearing menu only works in IE,
but it hopefully degrades nicely on other browsers).
Most recent happenings:
It is now possible for people to edit the details on ciphers that they have
submitted. If you have a cipher to your name, then create an account and email
me to have control of your cipher activated. It's a very basic interface, but
it's a step in the direction of having automatic cipher submission. Uploading
files is not yet available, and uploading is not an active area, as in most
cases I'd like to know when something changes in the implementation of the
cipher!
Also added is a table that lists the performance of the submitted ciphers.
There's quite a spread in the speeds at the moment, with the top cipher pulling
off nearly 120mbytes/sec, and the slowest only managing 1.82 mbytes/sec. Of
course, this is all on an x86-32 machine, and there is already one cipher in
there that will run a *lot* better on 64-bit machines.
Source code (only tested in MSVC,
though I'd like to eventually get it working on multiple platforms/compilers)
and Windows binaries are available
for download also.
