Okay, in today's installment I'll reply to my friend Kris Nuttycombe,
who read yesterday's installment and then asked how the storage
service provider could provide access to the files without being able
to see their filehandles and thus decrypt them.
I replied that the handle could be

Watching the rump session online briefly last night, I saw that some
interesting new results on MD5 and AES seem to have been discussed at
the conference. Would anyone care to give us a brief overview for the
mailing list?

OT trivia: The idea actually predates either monotone or git;
opencm (http://opencm.org/docs.html) was using a similiar

Getting back towards topic, the hash function employed by Git is
showing signs of bitrot, which, given people's desire to introduce
malware backdoors and legal backdoors into Linux, could well become a
problem in the very near future.

Target collisions for MD5 can be calculated in seconds on a laptop,
based on just a small change in the first block of input. There was
also a semi-successful demo of MD5 certificate problems; you could
join the special wireless network, and any https connection would be
silently proxied

I believe attacks on Git's use of SHA-1 would require second pre-image
attacks, and I don't think anyone has demonstrated such a thing for
SHA-1 at this point. None the less, I agree that it would be better if
Git eventually used better hash

More like this, please! The rump sessions have a lot of value (beyond the
often-strained attempts at humor).

The longer that MD5 goes without any hint of preimage attacks, the
less certain I am that collision attacks are even related to
preimage attacks.
I believe that yesterday, at the rump session at Crypto, restricted
preimage attacks were described. Not
Dear all:
A revised document has been posted at
http://www.connotech.com/doc_rw_sign_basic-02.html, including a fix for
an elementary security issue (and two other items, see document revision
history).
I received some, but not much, feedback (positive) on the first version.
Regards,
