Debian Archive Signing Key to be changed

February 9th, 2011

The Debian Project wishes to announce the change of the GNU Privacy Guard key used to digitally sign the archive reference files. Signatures are used to ensure that packages installed by users are the very same originally distributed by Debian and have not been exchanged or tampered with.

Affected distributions are the Debian unstable branch (codenamed Sid) as well as the testing branch (codenamed Wheezy). The Debian Security (security.debian.org) and Backports (backports.debian.org) archive also start using the new key now. The current stable version Debian 6.0 (codenamed Squeeze) and the current oldstable version Debian GNU/Linux 5.0 (codenamed Lenny) will have their ftpmaster signature updated with their next point release.

The new key has already been distributed via the debian-archive-keyring package and is included in all current releases of Debian.

Starting with the next mirror update this evening only the new key will be used.

For reference, the old key is:

  pub   4096R/55BE302B 2009-01-27 [expires: 2012-12-31]
        Key fingerprint = 150C 8614 919D 8446 E01E  83AF 9AA3 8DCD 55BE 302B
  uid                  Debian Archive Automatic Signing Key (5.0/lenny) <ftpmaster@debian.org>

and the new one:

  pub   4096R/473041FA 2010-08-27 [expires: 2018-03-05]
        Key fingerprint = 9FED 2BCB DCD2 9CDF 7626  78CB AED4 B06F 4730 41FA
  uid                  Debian Archive Automatic Signing Key (6.0/squeeze) <ftpmaster@debian.org>

This key rollover is a normal maintenance task and was started in August 2010. For security reasons Debian's archive signing keys regularly expire after three years.
