My current OpenPGP key was generated by GnuPG; it has the id 0xC785B90B5053A3A2 and its fingerprint is:

125B 5A0F DB78 8FDD 0EF4  1A9D C785 B90B 5053 A3A2

The previous, deprecated key has id 0x7640947667756F5D and fingerprint:

1645 B6EE 8311 1A03 03F2  B896 7640 9476 6775 6F5D

You can download both keys from wwwkeys.pgp.net. You can usually search by name or by id (in which case you'll probably have to include the 0x prefix). Be sure to check the fingerprint of the key you have downloaded in any case.

If the wwwkeys.pgp.net server you contacted is having problems, you can still download my current key from here (old one here), but this may be less up-to-date than what you should find on wwwkeys.pgp.net.

Here follows my “official” transition statement from key 0x7640947667756F5D to 0xC785B90B5053A3A2, signed by both of these keys:

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1,SHA512

                                              Friday, April 29th, 2016

Hello,

Because of weaknesses discovered about the SHA-1 hash function, I have
created a new OpenPGP key in March 2010, and been transitioning away
from the old one.

The old key is now deprecated; I prefer all correspondence to come to
the new one. I would also like this new key to be reintegrated into the
web of trust. This message is signed by both keys to certify the
transition.

The old key was:

pub   dsa1024/0x7640947667756F5D 2000-01-14
      Key fingerprint = 1645 B6EE 8311 1A03 03F2  B896 7640 9476 6775 6F5D

and the new key is:

pub   rsa4096/0xC785B90B5053A3A2 2010-03-17
      Key fingerprint = 125B 5A0F DB78 8FDD 0EF4  1A9D C785 B90B 5053 A3A2


You can fetch the new key from a public key server:

  gpg --keyserver pgp.mit.edu --recv-keys C785B90B5053A3A2

or, alternatively, from my web page:

  wget -q -O- http://frougon.net/OpenPGP-key.asc | gpg --import -

You should verify that the key you imported with this command
(C785B90B5053A3A2) has the same fingerprint as stated above in this
document:

  gpg --fingerprint C785B90B5053A3A2

If you have my old key in your keyring, you can now verify that the new
key is signed by the old one:

  gpg --check-sigs C785B90B5053A3A2

If you are satisfied that you've got the right key, and the UIDs match
what you expect, I'd appreciate it if you could sign my new key:

  gpg --sign-key C785B90B5053A3A2

and upload the resulting signatures to some place where I can find them.
You can send them to me by e-mail like this (if you have a functional
MTA on your system):

  gpg --armor --export C785B90B5053A3A2 | mail -s 'OpenPGP Signatures' f.rougon@free.fr

or, alternatively, upload them to a public key server:

  gpg --keyserver pgp.mit.edu --send-keys C785B90B5053A3A2

Thanks in advance. Please let me know if you encounter any trouble with
these instructions, and sorry for the inconvenience.

Regards,

Florent Rougon
