Hash: SHA256,SHA1

I am transitioning GPG keys from an old 1024-bit DSA key to a new
4096-bit RSA key.  The old key will continue to be valid for some time,
but I prefer all new correspondance to be encrypted in the new key, and
will be making all signatures going forward with the new key.

This transition document is signed with both keys to validate the
transition.

If you have signed my old key, I would appreciate signatures on my new
key as well, provided that your signing policy permits that without
reauthenticating me.

The old key, which I am transitional away from, is:

  pub   1024D/F2C423BC 2000-03-06 Stefano Zacchiroli <zack@upsilon.cc>
   Primary key fingerprint: 8156 FBF9 3EC1 D872 722D  3632 D5CA 9B04 F2C4 23BC

The new key, to which I am transitioning, is:

  pub   4096R/6D866396 2010-09-27 Stefano Zacchiroli <zack@upsilon.cc>
   Primary key fingerprint: 4900 707D DC5C 07F2 DECB  0283 9C31 503C 6D86 6396


To fetch the full new key from a public key server using GnuPG, run:

  gpg --keyserver keys.gnupg.net --recv-key 9C31503C6D866396

If you have already validated my old key, you can then validate that the
new key is signed by my old key:

  gpg --check-sigs 9C31503C6D866396

If you then want to sign my new key, a simple and safe way to do that is
by using caff (shipped in Debian as part of the "signing-party" package)
as follows:

  caff 9C31503C6D866396


Please contact me via e-mail at <zack@upsilon.cc> if you have any
questions about this document or this transition.
