[Bug 6223] New: distro signing key is unsafe

https://issues.apache.org/SpamAssassin/show_bug.cgi?id=6223

           Summary: distro signing key is unsafe
           Product: Spamassassin
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: Building & Packaging
        AssignedTo: dev@spamassassin.apache.org
        ReportedBy: jm@jmason.org


http://www.apache.org/dev/release-signing.html notes:

'Committers with a DSA key or an RSA key of length less than 2048 bits should
generate a new key for signing releases. The original key does not need to be
revoked yet.'

our sa-update signing key is 4096-bit RSA, but 
http://www.apache.org/dist/spamassassin/KEYS uses a 1024-bit DSA key :(

http://www.apache.org/dev/key-transition.html details what we need to do.

As discussed on dev@ list, it is time to generate a new key using these
apache.org recommendations.  We need someone who knows the old key passphrase
to generate the new key, then sign it with the old key.  We need the key in
order to do the beta and final release of 3.3.0. 

We also need to discuss expanding the group of signers to active members of the
project.

it would be nice to do this for 3.3.0 (but not required... yet)

> http://people.apache.org/... is the new key

I think a private key should be a closely guarded secret (not freely
accessible), much more so than its password. A password (say 40 characters
times 6 bits = 240 bits) is a much weaker target than 4096 bits of a
private key.

done!
http://people.apache.org/~jm/KEYS.bug6223 is the new key (and the old one, to
allow verification of old releases, until we eventually kill it off).

http://www.apache.org/dist/spamassassin/KEYS has been updated, and will update
as the mirrors update.

The key uses the same passphrase as the old one did.  Now to tell more people
what that is ;)
