Revocation of Zimmermann's fossil key

[Philip Zimmermann <prz@acm.org>]

-----BEGIN PGP SIGNED MESSAGE-----

To whom it may concern:

I have revoked my oldest PGP key, keyID FF67F70B, user ID 
  "Philip R. Zimmermann <prz@sage.cgd.ucar.edu>"
which should no longer be used.  Instead, use my newer key,
keyID C7A966DD, with user ID
  "Philip R. Zimmermann <prz@acm.org>"
The new key has been distributed with all PGP versions since version
2.3a in 1994.

My old email address at the sage site will soon disappear, so I'm 
revoking my old key.  I keep getting mail at my old address at sage
because people get that old address from my old key.  I can't just
revoke my old userID, so I have to revoke the whole key to get people
to stop using it.  Below is my revocation certificate, which I created
shortly after I generated my new key in 1994.  Please discontinue the
use of my old key and my old email address.  Note that this revocation
does not imply that my old key has been compromised.

 -Philip Zimmermann

Here's my old public key with the revocation certificate...
